Yes i followed it all. The test works, I port forwarded and all of that. Still same port error and I still can't connect. Double checked the firewall. I had it on UPnP then I port forwarded. Changed back to UPnP as i'm sure. Im not running under a router. Can't figure out why this is happening. Though the only thing I installed lately is Windows Defender Beta. I'm sure it's not that because it worked fine when it was installed. All this happened when i upgraded.
