Do you get this error when connecting to your own computer?
Error 15107 typically happens when your hosting computer uses a very high resolution monitor or ultra wide resolution monitor, but the encoder on the GPU cannot handle that resolution because it's too much data. Please change your resolution on the hosting PC to less than 4K or request a lower resolution when you're connecting to the hosting computer via the Parsec resolution settings.
Do you get this error when connecting to your friends computer?
Your friend (who is hosting) has their monitor set to a too high resolution. Tell them to turn down their screen resolution, to something like 1920x1080 @ 60hz.
