Does anyone have any experience with antstream? I was looking to get back into retro games, and this seemed like it might be a viable option?

I just moved and changed Wi-Fi, it's the same provider but, of course, the IP is different. Previously, I had zero issues with using Parsec, we logged in the first time and it worked like a charm. However, now, it doesnt work. I've opened the UPNP from the network site, given ports access and everything the site reccomends. I'm on Windows, thanks for helping in advance.
