Describe the Bug

After upgrading to 1.14.1 (from 1.13.1), collabora code server which is served as a public resource without authentication is no longer accessible.

When calling by opening a document from Nextcloud you receive an error message saying socket connection cannot be established,

Error is due to traefik upgrade - found the solution in https://www.reddit.com/r/selfhosted/comments/1ph9jio/traefik_v364_breaks_nextcloud_officecollabora/

traefik_config.yml has to be edited with new entries under entrypoints.

This is not a bug in Pangolin - merely a placeholder so the solution can be found for others having similar issues.

Thanks
Frank
