Have a look in System Preferences -- Security -- Firewall -- Advanced --

Scroll down thru the Processess that have already been granted "Allow Incoming Permissions" to

I strongly suspect that SooloosHelper and SyncCompanion will not be listed there and without them being given access, then Control:Mac just will not work at all.

I suggest you use Appcleaner again to remove any vestiges of Control:Mac.

Turn Off Firewall completely.
Restart your Mac with firewall off.
After Restart make sure the Firewall is still off.

Now install Control:Mac again.

Grant Incoming Permissions to those 2 Processes above.
