unable to connect to P2P session#305

I am unable to connect to my friends and vice versa when using a P2P session. When i host my friends get the same errors i get when trying to connect to them. It seems like TTS is unable to connect to steam and then to my friends.

I have the inbound connection rules set up for Steam and TTS. The connection has also worked for a brief period of time but then cut off the connection after a few minutes.

i also have been able to connect to friend sessions in other games on steam. so this issue appears to be isolated to TableTop Simulator alone.

I have had this problem for 4 MONTHS and still looking for a solve.
