a Nextcloud instance on my own Nextcloud server (Docker). At the moment version is 29.0.6.
I mainly use Talk and some file sharing. However, the main use is the Talk app for Android.
For a few days now, the Talk app for Android doesn’t work from mobile networks but only if I’m connected to a WiFi network.
This applies to all of my users, regardless of the mobile network. However, I can easily log into my instance and use Talk via the browser.
I am a bit confused because everything worked before.

Dieter
