Hi,

from the error messages you provided, it looks like you have a network connectivity issue from your forman to your smart-proxy server. If I had to guess, it would assume some firewall problem, but it might be any kind of network problem.
You should make sure that:

  • Port 9090 on your Proxy server is not blocked by a firewall from your Foreman server
  • Routing is properly configured between your proxy and the Foreman server
  • Check network connectivity is properly working on both systems.

Hope this helps.
Regards

Another suggestion what could be wrong as I see you did not give a port in the URL, so it is likely you forgot about the port (normally it is 8443 or 9090, not 443).

Thanks @Dirk @areyus. Able to connect by allowing port 9090.

Glad it worked, please mark either Dirk’s or my answer as solution so other forum members can easily see this issue is resolved :slight_smile:
