Solved iOS app no longer connecting via Wi-Fi

[GFAX]

All the sudden, none of the 3CX iOS apps will connect. Checked the troubleshooting 3cxphone.txt log and it shows "a server with the specified hostname could not be found" and verified this via Safari web browser as I cannot reach 3cx.cloud on any of my iOS devices. No problems on PC desktop, using the same network. If I turn off WiFi on the phone to connect via the mobile phone network, it will connect no problem.

Turning off Limit IP Access Tracking and Private IP address settings in iOS WiFi do not fix this.

Your issue is network related issue. You need to check on your local firewall which the WiFi connection is unable to resolve the FQDN.

I was able to resolve the problem by setting DNS to Manual and adding Goggle DNS 8.8.8.8

Glad to know this is resolved
