I have seen this few times (still investigating), I would ask you to send logs but logs are not working at the moment too (should be fixed in a day). For now could you try uninstalling and installing again? ---

Also could update system in Settings - Updates and then send logs to support if you see this error again please? ---

Is it necessary to add a identity server to find and finally chat with users on own Matrix-Server? If yes, it seems so, that only external servers like [matrix.org](http://matrix.org) works. The own “home”- Matrix-Server address do not work for … So personal informations will sent to this external server… ☹ [Next page](https://syncloud.discourse.group/t/matrix-server-error/313.md?page=2)
