Not able to set ip other than default for a tunnel

Hello, I am just trying to set up a valheim server through playit.gg. I’m all signed up and everything and my email is verified. I cannot connect to valheim using the default IP shown when you first make click add a new tunnel. I click no and enter the IP address I can locally connect at, but when I click the “set” button nothing happens. There is no recognition and nothing changes and if I click “go back” it just shows the default IP again.
