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?
Reinstall don’t fix the problem. Error message still existing.
I update system - error still existing. I send you logs.
Did you sent logs after updating system?
Did you check include support?
Yes.
Yes.
I redirect support mail, so i hope you get logs now ?
When did bought/build this device?
Probably writing the latest device image would fix it.
Pushed another version, could you update to see if that helps?
Thx! Error message is fixed. There is a new one:
Registration is disabled on “matrix.xxxx.xx”.
Yeah, use Users app to add more users.
Can you login with your main user?
Thx Boris - it works! Later I will test adding new users …
OK, what’s the trick to add users? Everytime comes error message “The account identifier (Username) is invalid” ?
Can you send a screenshot?
Sorry error is not clear, username should start with lower case .
OK - it works. Big thx! 
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 works. The own “home”- Matrix-Server address do not work for … So personal informations will sent to this external server…
