Facing this error while reactivating license failure. Tally support shows:
Cause
This error occurs when the antivirus or Firewall is blocking communication with the Tally server.
Solution
Add Tally.exe and Tallygatewayserver.exe to the Firewall exceptions list .
Any known solution on how to do this in Crossover. I tried to activate the license by disabling Firewall as well as Antivirus (Kaspersky) protection in Mac but didn't work.
