Authentication failed when trying to login through nginx reverse proxy

[ambipur76]

Operating system: Debian 11 x86 (Linux -hostname removed- 5.10.0-10-686-pae #1 SMP Debian 5.10.84-1 (2021-12-08) i686 GNU/Linux)
AirDC++ version: AirDC++w 2.12.1 i686
Web UI version: 2.12.0
Nginx version: 1.18.0

I run into "Authentication failed: Cannot connect to the server" when trying to login through myhostname.hu/airdcpp, however via 192.168.1.1:5600 everything works fine.

I have applied /etc/nginx/sites-available/lanproxy with the following content:
server {
listen 192.168.1.1:80;
server_name mydomain.hu;

    access_log                    off;
    include                         snippets/error_pages.conf;

    include                         snippets/proxy*.conf;

}

I have also configured etc/nginx/snippets/proxy-airdcpp.conf with the following content:
location /airdcpp/ {
proxy_pass http://192.168.1.1:5600/;
gzip_types text/plain application/javascript;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
auth_basic off;
}

My other reverse proxied services are also working fine. Could someone support me to investigate this problem? Thank's in advance!

I run into the same issue when trying to login to the site behind nginx. I use nginx proxy manager for setup and configuration.

Solved it. Websocket support needs to be enabled. screenshot of what worked for me.

@ambipur76 were you able to solve this?

[ambipur76]

Unfortunately not. I have no GUI like the above screenshot. I would be glad to know what and how this GUI setting "Websocket Support" changes nginx configuration.

Nothing useful in the nginx logs? The config looks correct.

Oh and what kind of certificate are you using for HTTPS? Better check the browser console log too.
