Proxy Error 502 Ubuntu Server 18.04

Hi I want to install xenforo, I followed this documentation to install SSL

[login to view URL](with-letsEncrypt-&-Certbot)

Unfortunately I access the site to install it and I get this error:

Proxy Error

The proxy server received an invalid response from an upstream server.

The proxy server could not handle the request

Reason: DNS lookup failure for: [login to view URL]:[login to view URL]

Apache Server at [login to view URL] Port 443

Could anyone help me to fix and install xenforo on my server?

Thank you
