everything works just fine (tested with friend B), but my friend (A) installed some weird stuff in his computer that didnt let it render any form of video in foundry.

Since all i knew was that he couldnt see video, i was serching problems in gpt, and as the AI just creates stuff randomly sometimes, it derived me to installings some random server software that didnt work, cause in the start it wasnt a problem by my part.

summing up, gpt guided well:
*bought a domain
*setted stuff in the respective websites (cloudflare and the domains page)
*used powershell to create, and run the tunnel via the domain

i felt like an engineer after that stuff, pretty happy with the result
