I’ve linked a previous post with details of the problem at the bottom of this post. The Seafile manual needs to be updated with the following solution.
Summary of issue:
Since the release of 6.2.X, the WebUI redirects (to port 80) when using an alternate port number in NGinx.
Solution:
In the Nginx config file for the site, the solution is to replace this line:
proxy_set_header Host $host;
with this line:
proxy_set_header Host $host:$server_port;
Requesting that the manual be updated with this information.
