Hi! If anyone is like me and ended up here after going down many rabbit holes to get swag working, turns out this section of the code should be commented out or removed. Apparently, websockets support changed around version 1.8 in swag, and shouldn't be dealt with directly in the proxy-confs anymore. You can see similar settings have moved over to proxy.conf instead. I used @Stitch0815 's .conf entirely (swapping in my server details), removed this section, and now I have the login page showing up correctly, players able to log in and access the vtt. https://github.com/linuxserver/reverse-proxy-confs/issues/198
