The page you link to says """ Add the client certificate and the key that will be used to authenticate NGINX on each upstream server with proxy_ssl_certificate and proxy_ssl_certificate_key directives: """ and the documentation for those directives is at http://nginx.org/r/proxy_ssl_certificate Those files relate to the client certificate that nginx will offer to the upstream server in order to identify itself. > What is trusted_ca_cert.crt;? http://nginx.org/r/proxy_ssl_trusted_certificate That file allows nginx to verify that the certificate presented by the upstream server, is one that nginx is willing to consider acceptable. > Is this related to backend.example.com? how can i obtain this? Yes; the Certificate Authority that signed the backend.example.com certificate should make this available to anyone they want to trust them. > But getting below exception when i hit the API. > > upstream SSL certificate verify error: (19:self signed certificate in > certificate chain) while SSL handshaking to upstream, client: <user_ip>, > server: <nginx_server_ip>, request: "POST /getsomething HTTP/1.1", upstream: > "https://backend.example.com:443/getsomething", host: "nginx_server_ip" I believe that that says that nginx (as the client) does not accept the certificate provided by the server at backend.example.com; probably due to nginx's proxy_ssl_trusted_certificate configuration not being what it expects.
