Link to NextCloud incorrect in confirmation email and in emails from shared files

Hello,

I have NextCloud running on a subdomain at all-inkl.de.

When I create a new user or want to share a file, for example, the link to NextCloud in the corresponding emails is incorrect.

The correct link would be: cloud.domainname.de

However, another dot appears in the email: cloud…domainname.de

Does anyone have an idea why this could be?

The data is stored correctly in the config/config.php file.

Thanks in advance

Peter

There is a longer issue on the bug tracker, in the very end they link a potential fix to test:
