The earliest recollection of this bug is traced back to PAN-OS 8.1 - July 22, 2025. This bug is fixed in PAN-OS versions 8.1.17. Fixed an issue where, on Panorama, context switching to the web interface of a managed firewall running PAN-OS 8.1.16 did not work. On the Panorama management server, you cannot context switch to the web interface of a managed firewall running PAN-OS 8.1.16. Workaround: Downgrade the managed firewall to PAN-OS 8.1.15 or earlier release.
