App is Disconnected. Waiting for network while on Corp Wifi network

[jstreit]

Recently my 3cx android app has not been able to connect to the 3cx server while on our Corp Wifi network, which the server/PBX resides on. It used to work fine. I can ping the server/PBX using both the internal address and external address listed in the Account information from the phone itself. As soon as I turned off the wifi it connects no problem. I am not sure where else to start looking so I am starting here.

i've seen posts here about this - maybe talking about IPv6? but not 100% sure.

If the phone, when connected to Wifi, works for other Data applications just fine, then my suspicion would be that it is not able to resolve the FQDN when on the local LAN. I also assume that you are using the FQDN, and not the local IP of the 3CX server, in the phone settings. Is it the IP or the FQDN that you are pinging?

Is this the only (3CX soft phone) device you've tested? You say it began recently, where there changes made t the network, or anything else?

Are there any, 3CX Activity Logs when registration is attempted.

Two identical model Android phones. One has the 3CX app version 15.5.342.392. Works fine. The other has version 15.5.344.492 and gives "Disconnected. Waiting for network" whether connected via LAN or via WAN. (Phone on Wi-Fi in both cases). Both phones show with green dots under Extensions and both show as "Provisioned" under Phones. Invoking Reprovision from 15.5.344.492 app menu gives "Cannot contact provisioning server because of a network issue". Other app succeeds.

Have rebooted phone. Have stopped and restarted app. Have uninstalled and reinstalled app. No joy. 3CX is 15.5.15502.6.

No IPv6 in use.

Looks to me that the later version of the app has a problem.

Looks to me that the later version of the app has a problem.

Have now done the obvious test of downgrading the app from 15.5.344.492 to 15.5.342.392. Copied the apk from the OK phone and installed on the problem one. On completion the installer asked if I wanted to open the app. I OK'd that and it worked properly immediately. No other changes to the phone or PBX. No manual reprovision.

Went to the Playstore and updated the 3CX app. "Disconnected. Waiting for network" issue returned immediately.

Downgraded again. Immediately working.

I'd say that conclusively points to the app.

Thanks, we'll check this and try to have a fix for the next release.
