## PANG-7012
Fixed an issue where the embedded browser for Prisma Access Agent
did not reuse the Windows Hello token for reauthentication, forcing
users to manually enter their credentials despite having Windows
Hello enabled on their devices. The embedded browser now properly
leverages existing Windows Hello authentication tokens for seamless
reauthentication without requiring manual credential entry.

## PANG-6738
Fixed an issue where certificate authentication failed on Windows
devices when certificates were stored in the machine certificate
store, preventing the Prisma Access Agent from properly
authenticating users with machine-level certificates. The agent now
correctly accesses and utilizes client certificates from the machine
certificate store, eliminating the need to manually import
certificates to the user's personal certificate store as a
workaround.
## EPM-4616
Fixed an issue where newly added internal gateways werent
visible in existing Prisma Access Agent settings, preventing
administrators from updating agent configurations with recently
added internal gateways. The agent settings now automatically
refresh to display all available internal gateways, including those
added after the initial configuration, eliminating the need to
create new agent settings to access newly added gateways.

## PANG-7949
Fixed an issue where the Dynamic Privilege Access enabled Prisma
Access Agent was unable to connect to a gateway after upgrading an
endpoint to Windows 11 24H2. Following the Windows upgrade, the
Prisma Access Agent would lose the ability to establish gateway
connections, even though the Endpoint Manager (EPM) connection
remained functional. This issue occurred consistently across systems
that had undergone the Windows 11 24H2 upgrade, affecting the
agent's ability to connect to any configured gateways while
maintaining normal endpoint manager connectivity.
## PANG-7865
Fixed an issue where the Prisma Access Agent on Windows did not
properly honor updated session timers after a user extended their
session through the embedded browser. The agent now correctly adopts
the newly extended session duration when users authenticate through
the session expiry banner, preventing premature session termination
and ensuring the Prisma Access Agent icon remains responsive in the
system tray throughout the extended session period.
## PANG-7960
Fixed an issue where the Prisma Access Agent on Windows blocked
authentication in the embedded browser due to the
Best Available - Fail Safe mechanism
in the forwarding profile triggering during the initial
connection attempt. The embedded browser now properly bypasses
the fail-safe mechanism when the agent is configured to run in
on-demand mode, enabling successful authentication on the first
attempt without requiring users to cancel and retry the
authentication process after a reboot.
## PANG-7309
Fixed an issue where the Prisma Access Agent on Windows failed to
automatically switch from an external gateway to an internal gateway
when the user's device woke from sleep mode after being connected to
different network environments. The agent now properly detects
network changes upon waking from sleep. It also automatically
switches to the appropriate internal gateway without requiring
manual sign-out via the pacli epm signout
command and subsequent reauthentication through the Prisma Access
Agent app.

## PANG-9620
Fixed an issue where the Prisma Access Agent would automatically
disconnect and remain disconnected without attempting to
reconnect, leaving users without network protection. The problem
occurred when the agent lost its connection to the endpoint
management server and failed to re-establish the connection
automatically as expected.
This occurred due to a DNS resolution timing conflict in certain
network environments where the primary DNS server was
unresponsive while the secondary DNS server was functioning
properly. The fix adjusts the DNS resolution process to ensure
proper failover occurs when the primary DNS server is
unavailable, allowing the agent to maintain connectivity and
automatically reconnect when network issues are resolved.
## PANG-9630
Fixed an issue where the Prisma Access Agent would become stuck
in a "Connecting" state after a network switch when attempting
to connect to an internal gateway. This problem occurred when
users experienced a network change that caused them to be logged
out from the tunnel, and while the Prisma Access Agent endpoint
manager web-socket would successfully reconnect, the Prisma
Access Agent app would remain stuck displaying "Connecting"
indefinitely.
## PANG-9276
Fixed an issue where the Spyder application would display
"Permission denied" errors and fail to work properly when Prisma
Access Agent was installed on the same computer. Users found
that Spyder would only function normally after completely
removing the Prisma Access Agent from their system, creating a
conflict between the two programs. The fix ensures that the
Prisma Access Agent no longer interferes with Spyder, allowing
both programs to run simultaneously without conflicts while
maintaining the agent's security protection for other
applications on the system.
## PANG-9220
Fixed an issue where users encountered "Server Enrollment
failure" errors after installing Prisma Access Agent version
25.4.0.29, preventing them from successfully connecting to their
organization's network. The problem occurred during the initial
setup process when the agent attempted to register with the
endpoint management server but failed with messages indicating
an invalid enrollment secret. This occurred due to a
compatibility issue between the agent's security enrollment
method and certain Windows system security components. When the
agent tried to use the primary secure enrollment process, some
Windows systems would reject the connection due to unsupported
security protocols, causing the entire enrollment to fail.
## PANG-9092
Fixed an issue where the Prisma Access Agent would freeze and
become stuck in a non-responding state. The problem occurred
when the application attempted to update multiple settings at
the same time from different parts of the program, causing
conflicts that would lock up the entire application. This
resulted in users being unable to interact with Prisma Access
Agent, as the interface would stop responding and the agent
would appear to hang indefinitely. The fix ensures that all
setting updates are now processed in a controlled, sequential
manner to prevent these conflicts and maintain application
responsiveness.
## PANG-9067
Fixed an issue where the Prisma Access Agent on macOS 15.6.1 failed to connect to external gateways when selecting Best Location and incorrectly switched to internal connectivity. This issue manifested in two specific scenarios:
1. After upgrading the operating system from macOS 15.6 to 15.6.1, Prisma Access Agent would incorrectly connect to an on-premises gateway instead of maintaining its connection to the external Prisma Access gateway that it was using prior to the OS upgrade.
2. When users selected Best Location from the Prisma Access Agent app, the agent would search through all available Prisma Access gateways but then inappropriately switch to Internal mode, even when connected to a home WiFi network where Internal Host Detection should not be triggered.
This occurred due to the improper cleanup of the on-premises tunnel routes during the Best Location selection process, which caused the system to incorrectly determine that it was on an internal network and activate the Internal Host Detection functionality. This resulted in users being unable to establish proper external gateway connections through Prisma Access Agent on the updated macOS version, forcing the agent into internal mode when external connectivity was required and available.

## PANG-8845
Fixed an issue where the Prisma Access Agent would incorrectly
remain bound to port 0 when switching between Prisma Access
Agent endpoint manager configurations with different proxy
settings, causing endpoint traffic to Explicit Proxy (EP) to
fail. This problem occurred when the agent initially connected
to an endpoint manager without agent proxy configured, then
switched to a different endpoint manager that had a proxy port
configured, but failed to update its port binding from port 0 to
the new proxy port. The agent now correctly updates its port
binding when switching between endpoint manager configurations
with different proxy settings, eliminating traffic routing
disruptions.
## PANG-8200
Fixed an issue where the Prisma Access Agent on Windows devices
would incorrectly display the previously connected server FQDN in
the Server Name field after executing the pacli epm
signout command without the --keep
parameter, instead of properly resetting to show Select
Server Name as expected. This inconsistency between
Windows and Mac platforms has been resolved, ensuring that both
operating systems now consistently reset the login view and display
the default Select Server Name prompt when
signing out without preserving server information.

Fixed an issue where the PASrv service would crash and generate
crash files on a newly installed Prisma Access Agent running in
Always On mode on Linux systems. The crash occurred after user
sign-in during the tunnel connection process while the agent was
operating in Always On mode. This issue affected Linux environments,
particularly Ubuntu 22 x86 systems.

## PANG-9242
Fixed an issue where the Prisma Access Agent on macOS and Windows
would fail to properly clean up tunnel interface routing table
entries when executing the pacli epm
signout command after a gateway shutdown had
left the agent in a Disconnected state. This problem occurred
when agents that were previously connected to a tenant became
disconnected due to gateway shutdowns, and users subsequently
attempted to sign out using the pacli
command.
## PANG-8945
Fixed an issue where the Prisma Access Agent Manager would
incorrectly handle ICMP traffic configuration after upgrading to
the latest version. When the Block Non-TCP and
Non-UDP based traffic when connected to tunnel
option was disabled by default following an upgrade, the
pacli traffic show command would
inaccurately display Allow non-tunnel outbound ICMP
when connected to tunnel as true, while the
underlying Allow ICMP for troubleshooting
value was incorrectly being passed as false instead of the
expected true value.
The agent now properly synchronizes the ICMP traffic
configuration values to ensure consistent behavior between the
configuration display and actual traffic routing.
## PANG-8929
Fixed an issue where the Prisma Access Agent on Windows would
incorrectly report "error: 513 - PASrv is unreachable, please
confirm it's running" when executing the pacli epm
status command during reinstallation scenarios.

## PANG-11201
Fixed an issue on Prisma Access Agents for Linux where the Prisma
Access Agent connection profile became stuck in an "activating"
state when NetworkManager was configured not to manage the
tunnel interface, resulting in a tunnel connect and disconnect
loop that prevented successful establishment of the tunnel.
## PANG-11153
Fixed an issue where the Prisma Access Agent on Linux experienced
recurring PASrv process crashes approximately every 20 seconds
due to abnormal termination during agent upgrade operations,
causing the agent to become unresponsive and preventing log
collection.

## PANG-11395
Fixed an issue where the Prisma Access Agent on Windows 11
laptops did not reauthenticate with the internal gateway when
transitioning between network interfaces (for example, from
Wi-Fi to LAN) and temporarily having more than one active
network interface. This prevented the IP-user mapping from being
updated on the NGFW firewall, causing traffic from the user's IP
to be unrecognized.
## PANG-11328
Fixed an issue where DNS resolution failed for Microsoft 365
services (MS Teams and Outlook) running Prisma Access Agents on
dual-stack Windows devices.
## PANG-11311
Fixed an issue where the Prisma Access Agent displayed an
erroneous "Your connectivity might be affected. Please try again
or contact your administrator" error notification when a user
manually disconnected from an on-demand connection.
## PANG-11293
Fixed an issue where Prisma Access Agent version 26.1 was unable
to retrieve the status of disk encryption for Host Information
Profile (HIP) reports, causing HIP checks to fail and denying
access to private applications.
## PANG-11284
Fixed an issue where, after upgrading to Prisma Access Agent
version 26.1.1.10 on Windows, users attempting to log in with
Microsoft Entra SSO experienced login failures and HIP check
compliance errors (Error 53000) because the embedded browser
incorrectly prompted for a plugin installation."
## PANG-11274
Fixed an issue on macOS devices where gateway connections would
fail or experience significant delays after waking from sleep.
This occurred because the Prisma Access Agent service (daemon)
attempted to access client certificates in the login keychain
through the user interface (UI) while the UI was still asleep.
These requests would queue up and process sequentially once the
UI woke, causing older requests to time out and preventing
timely gateway connections.
