Hello,
If you are seeing this error while trying to activate your Pro license, during the activation process, Zoiper tries to establish a https connection with 185.117.83.36 on port 443 TCP (The same IP that you will get by pinging cert.zoiper.com). Make sure that it is not blocked by your firewall or antivirus.
