Remote Desktop Connection Error?

Question

Remote access

Good afternoon, I set up a remote working elephant on another computer. Worth Windows 10 Pro. I enabled the remote desktop function, added a virtual server in the router with port 3389 and the local ip of the computer on the network. I'm trying to connect from another computer on a different network, via a common ip (c 2ip) and port 3389. It's loading and then it knocks out a connection error (remote desktop is not available). Help please

Tried the same without a router. Connect to a common ip, without a port and with a port. Everything fails early. I even tried with noip.

Answer 1

ip white?

Answer 2

What is your ip from your ISP? "White" (outer) or gray??

Answer 3

NLA on the destination host in what state - on or off?
Does the account under which you are logging in via RDP have sufficient rights to do so?
