Strange, I had the same issue for over a week when I downloaded it; Couldn't play. I opened the ports and it worked for me. Also, I saw you trying to join multiple timesi have checked ports on port forward's tool it is saying that they are open i don't know why it isn't working
Not sure what'd work for you. But some stuff you can try is deleting CacheSxS. Or downloading and running the latest version of the updater (I hope you tried this).
Although it shouldn't make a difference, I didn't open my ports from 192.168.1.1. I went to Windows Firewall settings and opened it from there.
