Docker & Nextcloud Sync and Oauth

Mokter

Hey guys,
so I’ve got Nextcloud an Mailbox running in docker each behind a proxy of nginx also docker powered. I found a tutorial about how to use oauth in Mailcow to login in Nextcloud. Followed that all the way and set everything up. When trying to access via the link now I get the following error:

error "redirect_uri_mismatch" error_description "The redirect URI provided is missing or does not match" error_uri "http://tools.ietf.org/html/rfc6749#section-3.1.2"

any one can help me out here? What else do I need to set up or what does cause this issue?

best regards,
Tom

The problem still persists. Any help appreciated…

Got the same problem and found a solution :-). Carefully re-read the instructions in the mailcow documentation, in detail the info box under point 2. There is a hint that you have to remove “index.php” from the Callback-URL if you installed nextcloud with the helper script. This worked for me.
