[X2Go-User] http proxy server for X2Go client

Hi everybody,

I am trying to set-up an nginx server as http proxy for the x2go client. My x2go server is a VM on a private network 10.10.10.201. So far I have been using an ssh tunnel to reach the server from outside via ssh on the host. The host runs an nginx server that is connected to the internet. I would like to use nginx as the http proxy to the ssh instance running on the VM. However, when I set "Use proxy server for http connection" and put the host sshproxy.mydomain.com and port 80 in the client, I alwas get the error message: "Cannot connect to proxy server". Nginx does not show any access in the log. Here is my Nginx configuration:

server { listen 80; server_name sshproxy.mydomain.com;

access_log  /var/log/nginx/sshproxy-access.log;
error_log  /var/log/nginx/sshproxy-error.log warn;


auth_basic "Restricted";
auth_basic_user_file htpasswd;


location / {
    proxy_pass http://10.10.10.201:22;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_read_timeout 3600s;
    proxy_send_timeout 3600s;
    proxy_connect_timeout 3600s;
}

} Can anyone help me to get this working?
