Pc Xbox party stuck in connecting

I had a similar problem, I solved it by changing how my pc was connected to the network.

• If the xbox is connected using wifi and the pc is connected using
  wifi if works.
• If the xbox is connected using wifi and the pc is connected using
  lan the xbox does not show on the pc.
• If the xbox is connected using wifi and the pc is connected using both
  wifi and lan the pc can initiate a connection to the xbox, but the xbox is stuck on a screen saying the pc is about to project.

I'm not sure if the wireless display standard requires both devices to be connected to wifi or if this was just pure coincidence, and has more to with the ip-addresses and subnets used on different networks?

Streaming the opposite way around (form the xbox to the pc) works in all configurations.

Does your PC run Windows 10? If so: Were you able to connect to Xbox Live on the Xbox App on your PC, and use non-web applications like party chat on your PC?

I'm havering the same problem with mine my nat type is stuck at strict to moderate and my mtu setting are stuck a 510 ever since the new preview update my Xbox is like useless right now can't connect to game party's and downloads are taking for ever any
news on a update would be very appreciated

the only way this would be possible is one of two solutions you connect your party through the Xbox app on your pc and talk through the pc on either Xbox party or discord voice chat. There is no way of doing it any other way, however. due to the party
chat being on a different channel on the Xbox to the audio of the game on the Xbox. Or you can stream through the Xbox to pick up the party chat this way but you won't be able to use Obs.

this is NOT resolved, playing fifa last night with friends, i stream, so running party chat through the PC. i COULD NOT connect to party chat at all. yet, had no server issues with xbox or fifa.
