NGINX 502 Bad-Gateway 1.12.2

[Shahi-Paneer]

Hi,

code-server was working perfectly fine until a few weeks ago it suddenly stopped working.

Here is my nginx config:

 events {

}
http {
server {
  listen 8081 ssl;
  listen [::]:8081 ssl;
    ssl_certificate     /var/cpanel/ssl/apache_tls/liemcomputing.ca/combined;
    ssl_certificate_key /var/cpanel/ssl/apache_tls/liemcomputing.ca/combined;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;



  server_name liemcomputing.ca;
  location / {
     proxy_pass http://localhost:8080/;
     proxy_set_header Host $host;
     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection upgrade;
     proxy_set_header Accept-Encoding gzip;
  }
}
} 

Whenever I try to access it I see this:

I have also received this error:

2021/06/02 22:48:38 [error] 11113#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client:[insert ip here] , server: liemcomputing.ca, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "liemcomputing.ca:8081"

I am using Centos Version 7.

Any help would be appreciated

Thanks.
