rFactor dedicated server help

Okay. You don’t need to know anything about rfactor for this one, i just need to know how to make avast let me connect to myself.
After installing avast and restarting, i cannot run a dedicated server from my computer and connect to it. I keep getting “join timed out”
This never happened before avast was installed. Therefore, im nearly 100% sure that it’s avast. If you have any other suggestions, please feel free to post.
Thanks for any help that can be provided. The sooner the help the better, cuz i want to get my server back up and running.

Welcome to the forum.
avast! doesn’t block, it only scans. Please make sure that you allow access in your firewall.
If avast is blocked, this may cause your problem.

well, i uninstalled avast to see if it was the windows updates or avast, and i can now connect to my server with avast uninstalled.
Avast is what was blocking me from receiving a connection from myself. I hope that i can get a solution though. i still want to use avast.
