External company configuration Test ECC Connection

External company configuration
After entering the ECC URL , I click ‘Test ECC Connection’ and get an error ‘Unable to connect to the remote server’ referencing an ip that it cant connect to, but it is not the ip of the address i put in the ECC URL field. What am I missing.
