Docker - Nginx Proxy Manager - Disable SSL verification for proxied host

Self-signed certs are not trusted by Nginx Proxy Server.

So disable certificate verification.

NOTE: It works like this:

  • intenet –> [ LE Cert ] –> NPM –> [Self-Signed cert] –> my_service

where

  • LE Cert - Lets Encrypt Certificate.
  • NPM - Nginx Proxy Manager.
  • Self-Signed cert - A Self-Signed Certificate.
  • my_service - The proxied host.

Go to your proxy host custom locations and define / (root) location.

With a URL to the proxied host

location / {
    proxy_pass https://self-signed.example.com/:443;
    proxy_ssl_verify       off;
    proxy_ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
}

With an IP Address to the proxied host

location / {
    proxy_pass https://123.123.123.123:9876;
    proxy_ssl_verify       off;
    proxy_ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
}

Other approach

Add this in advanced tab. 

location / {
    proxy_pass $forward_scheme://$server:$port;
    proxy_set_header Host test.com;
    proxy_ssl_name test.com;
    proxy_ssl_server_name on;
    proxy_redirect $forward_scheme://$server:$port /;
}
