you might like to have a look at the Caddyfile i came up with, it also loads avatars. note the use of handle_path instead of handle, it automatically does the stripping. also note that the example configures seafile in a non-root directory (e.g. https://seafile.example.com/seafile/ instead of https://seafile.example.com). if seafile resides at root level, simply replace the initial handle /seafile* with handle.
i’m only having trouble getting the notification server to work.
