IPSec VPN cannot connect to non-IP address LAN server

Dear All,

We have an IPSec VPN in the office that connects to our client’s server. They advised us to connect to the upgraded environment and gave us a new lan server of https://mtpnewenvironment.server.clients or that is not an ip address (they usually gave lan servers like this for example 192.168.1.1/clients). IPsec policies have established connections but we cannot have successful connections to https://mtpnewenvironment.server.clients.

Please help.

Any help will be highly appreciated. any one please?
