Shadow banned, never knew why, not even moderators, and never got an answer, so I figured it was better to just leave the place to somewhere with more humans at the helm

Are they really that naive and stupid?

can you share the config?

Without knowing your config is hard… but let’s try: Apache httpd needs “SSLProxyEngine on” directive to be able to proxy to https sites first (assuming you already loaded mod_proy and mod_proxy_httpd), and then when connecting it will check the name of the server as defined in the proxypass directive to see if the certificate on that server matches the name, it also looks for the date of expiration, if any of those fail it wont rev proxy, to ignore those you have to add directives for that, too, but better make sure names match and dates are fine.
