I'm currently running v5.9 which so far has been working well. I'm also using SWAG to run it behind a proxy. If I try to upgrade to 5.12 or 5.13, the proxy no longer works. It is still possible to login directly after the upgrade though. What seems to happen is that the container is seen by the proxy and it tries to load but it just constantly spins (with the Omada logo). It seems like it's getting stuck somewhere. I tried to go through the access logs but nothing obvious comes up in there between v5.9 and the alter versions. It jsut seems like something is no longer passing through but no error gets thrown. Does anyone have any suggestion on what to do? Many thanks in advance. Edit: Here's the proxy config (excuse the mess): server { listen 443 ssl; listen [::]:443 ssl; server_name webaddressofserver.xyz; include /config/nginx/ssl.conf; client_max_body_size 0; location / { proxy_set_header Host $http_host:18043; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Referer $http_referer; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass https:/UNRAIDLOCALIPADDRESS:18043; proxy_redirect ~https://(.+):18043/(.+)/login$ https://$http_host/$2/login; proxy_buffering off; } location /js { proxy_pass https://UNRAIDLOCALIPADDRESS:18043/js; } location /api { proxy_pass http://UNRAIDLOCALIPADDRESS:18043/api; } }
