Avast Firewall Blocking Synergy

Running Avast Free and Synergy on Windows machine. The Avast firewall is blocking the app from functioning. I have added both application and firewall rules to Avast and it still blocks the networking connection. Only disabling the firewall completely will allow the app to work. This just started within the last few hours so I can only assume Avast pushed out something that broke it. Can’t add the second screenshot cause dumb forum posting rules.
