Failed to initialize driver interface > [FAIL] Peer: <client address> Reason unknown

[Craftingcat99]

I've tried getting miraclecast to run as a sink for a few days now, but encounter the same error everytime. So far I've tried it on a clean ubuntu server install but, at first, ran into issue because of the missing gui. But even with ubuntu 22.04 (non-server, stock, clean) i can't get my phone, laptop or desktop to connect to the sink. I always get the same

[FAIL] Peer: <client address> Reason: unknown

error. Since the device is "sort of" headless and i'm not exactly a pro at working with linux, it's a bit hard to get a full log. But I managed to copy the part where the pair fails from the wifid process:

If tried to cast from a SAMSUNG S20+, a Thinkpad T480 with an AX210 wifi card and from my Desktop with a cheap TP-Link dongle. The sink is an old QNAP NAS with Ubuntu installed (not live!) on a Thumb drive and a tp link usb dongle which supports P2P. I installed miraclecast exactly as stated on the github page and ran both "compatibility test" scripts without errors. Have I overlooked anything? Any help would be much appreaciated. If you need a specific log i can see if I'm able to provide it,
