Solved FQDN problem

[mladen_indas]

Hello, I have an issue with the FQDN.
I can't access it through the web browser, and I see that's the reason why the mobile app isn't working.
Is this a global issue, or is it specific to our setup?
When I log in via the IP address, everything works fine. IP phones are also functioning without any problems.

Is this 3cx remote or local? If local, did configured split dns? Firewall check pass?

Yes, the issue was with DNS. We had set up forwarding on them, which caused this problem. Anyway, the issue has been resolved. Thank you for the quick response!
