Websocket comms error

General

Hi all,

i have upgrade nodered and nginx reverse proxy and with my configuration that was working for redirecting traffic by nginx has stopped working.

I am getting this error in access.log:

08/Jan/2021:17:32:46 +0100] "GET /comms HTTP/1.1" 400 11 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36"

My configuration is:

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name nodered.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    # enable for ldap auth, fill in ldap details in ldap.conf
    #include /config/nginx/ldap.conf;

    location / {
        # enable the next two lines for http auth
        #auth_basic "Restricted";
        #auth_basic_user_file /config/nginx/.htpasswd;

        # enable the next two lines for ldap auth
        #auth_request /auth;
        #error_page 401 =200 /login;

        include /config/nginx/proxy.conf;
        resolver 127.0.0.11 valid=30s;
        set $upstream_unifi nodered;
        proxy_pass http://$upstream_unifi:1880;

    }

    location ^~ /comms {
        # enable the next two lines for http auth
        #auth_basic "Restricted";
        #auth_basic_user_file /config/nginx/.htpasswd;

        # enable the next two lines for ldap auth
        #auth_request /auth;
        #error_page 401 =200 /login;

        include /config/nginx/proxy.conf;
        resolver 127.0.0.11 valid=30s;
        set $upstream_unifi nodered;
        proxy_pass http://$upstream_unifi:1880;
        proxy_buffering off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_ssl_verify off;
    }

}

What could be wrong?.

Thanks in advance

Unless there is something hidden in the included proxy.conf, you are missing some stuff that would allow websockets to work.

Using NGINX as a WebSocket Proxy

I have checked all backup config and it is the same in all files. I have although a unifi controller using websockets configured inside this nginx and it is working without any websocket error.
