Solved Some store apps unregistered after server migration to Azure

[sanch6]

Hello,

I migrated a PBX to Azure, and now 35% of the extensions (10 apps) are no longer registering with their Windows Store App. I've done similar migrations before without any problems.

Other extensions registered correctly on the same network.

I've already tried re-provisioning the app, repairing and resetting it from Windows settings, and restarting the computer. But nothing works.

The web app works. The extension registers correctly on another computer. The PBX's FQDN is resolved correctly. And what's even stranger is that the BLF status is reporting correctly; I see colleagues in green or red, and I can see ongoing calls in the manager panel.

Windows Store Apps version 5.4 (build 1076) 20.0.1076.0

Thanks for any suggestions.

The computer must have something firewalled off - perhaps via some AV software? That would be where I start to chase it.

Thank you, I'll ask the endpoints admin and let you know.

You were right, the firewall admin had to make some adjustments.
I didn't think about it before as other apps were working.
Thanks for you help, we can close it.
