Talk android app crash server

I haven’t logged into the app on Android for a long time. I tried to set up a turn server, and now everything works fine even without it on a PC in a browser. Resetting the app on the phone doesn’t help. I cleared the cache and date. All the same, with a clean installation from the store, the account data is already there. Now let’s talk about the worst thing. When launching the app, the Server crashes and freezes. This is incomprehensible, because the other functions work very well. I reinstalled the app on the server. I use the snap package on my machine, since apt get is not supported. Ubuntu core 18 arm64. It would be nice to try to at least completely delete the app cache. When launching the app, the chats that I deleted are displayed. After about 5 minutes, it writes that the connection is lost, I enter the server data, reboot the server and click enter. An interface appears with a log in button to add a user. After clicking the log in button, I see the old chats again. New ones do not appear. The server freezes and crashes.
