Summary
This thread discusses an issue with Nginx /.well-known/caldav not properly set up, which is causing a redirection from Chrome to a different URL. The solution involves removing a block from the Nextcloud nginx config and moving it to the reverse proxy part of the nginx config, and then adding /nextcloud/ to the reverse proxy part. Finally, regular expressions can be used to reference both carddav and caldav in a single line.
