Trying to make a beta 1.7.3 server

I am trying to run a beta 1.7.3 minecraft server, and i have the b1.7.3.jar server running on my computer, but attempting to join the playit ip+port does not work!
Does playit support beta?

just imagine the playitgg service as a tunnel from the outside world to your server, as long as you have it pointing to the right place, that mostly all that matters.

First couple things I would check would be your port on your MC server is the same as where playitgg is pointing. I don’t have experience with running a MC on windows, only linux, but I have ran into issues with windows and it’s built in firewall blocking ports. I’m the last person to try to talk/walk anyone through windows firewalls.
