I tried opening a port for RDP on my vDSL, even though i dont see how its related, because im not trying to connect to my computer, im trying to connect to a cloud server, which i also tried opening a port from the cloud server, and it didn't work. I also changed the port number from 3389 from the server to 3320 and 1350 to test from the registry. I was able to connect for 1 second and then i was disconnected and was never able to connect again. I don't know how to solve it.
I checked from PortCheckTool for 3389 port and it says its open
