Hello community,
I wanted to use Nextcloud with the mailcow oauth2 authentication, but somehow I do not get it to run like supposed. I get redirected to authorize the application and after that I get a message stating “Unable to exchange code for API access token. HTTP client error: Connection timed out after 30001 milliseconds.”:

Do you have any idea, what might cause the issue?
Thank you and best regards,
Nico
