Unable to register on apps.nextcloud.com

Not even sure if this is the right forum to ask…

But If I try to register for a new account at https://apps.nextcloud.com/ there are two options which both fail.

Username/Password => ReCaptcha points to the wrong host (google.com and required www.google.com)

OAuth2 with Github => Fails with a email confirmation that seem to give a mail that is broken.

What/where is the right way to guide this issue?

Thx,

Thorsten

Found out a few things:
=> The Email confirmation link mail was garbled and this could be solved by cleaning up the link in German translations by removing apps.nextcloud.com at the end.
