i am using curl in my local linux server to access my remote web service, and i found that both servers are reachable. But my issue is that Remote Server-1 is not accessible without "sudo" but my another server (Remote Server-2) is accessible without sudo.
OS: RHEL
Firewalld: Enabled -- 80,443 ports, https services allowed
Remote Server-1 --> Gives response with sudo
--> Gives Error "curl: (56) Received HTTP code 503 from proxy after CONNECT"
Remote Server-2 --> works & gets response with/without "sudo"
i dont understand why my Remote server-1 is not accessible in user level, where the other server is accessible. Both of these servers are in same environment.
Please help.
