At quick glance, the 'Unknown error' string seems to be coming from the server. Possibly something like: https://github.com/nextcloud/server/blob/332b3efdf0df6bd489d83f58e8ffa677749d0774/lib/private/Files/ObjectStore/SwiftFactory.php#L203

The main point with this issue is to provide the user with a better error message. Robin will check this on the server side.
