i've modified the url in config json and now work with this config :
location /forum {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://www.mysite.org:4567/forum; # no trailing slash
proxy_redirect off;
# Socket.IO Support
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
The problem is if i open https://www.mysite.org/forum it don't add the trailing slash and i try to open /forumcategories instead of /forum/categories , i've try to modify location to /forum/ but it give error if i try to open https://www.mysite.org/forum/ , any hint ?
