Cannot communicate after proxy IP change


When I change the IP address of a proxy foreman cannot connect to it anymore. DNS is still the same, only the A and PTR are changed to the new IP and I can telnet and also connect using the certificate from the foreman cli to the proxy

The proxy.log on the proxy doesn’t show anything on a refresh.

I have seen this in the past and most of the time removed the proxy and re-added it again but this is undoable. Any idea ?

Expected outcome:

Connection with proxy
