I have followed the instructions found in the article Running Apache Nifi behind a proxy. I am using nginx as my proxy server. I am currently getting 502 Bad Gateway errors when I browse to the proxy nifi url. In the logs for nginx I see this error: (peer closed connection in SSL handshake while SSL handshaking to upstream). I have done some troubleshooting using openssl s_client -connect.
When I run the openssl s_client -connect from the nginx proxy to the nifi server I get the following error 140658986932128:error:140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177:,
followed by a successful connection, however, the TLS session ticket is not displayed. I know this is a bit all over the place, but I have been trying to work through this for several days. Below is my location configuration for nginx. Any ideas or help would be greatly appreciated.
location /nifi {
proxy_set_header X-ProxyScheme $scheme;
p
proxy_set_header X-ProxyHost <proxy_hostname>;
proxy_set_header X-ProxyPort 443;
proxy_set_header X-ProxyContextPath "";
proxy_set_header X-ProxiedEntitiesChain $ssl_client_s_dn;
proxy_pass https://nifi/nifi;
}
