When you click Activate PRO you will see the same Activation screen as above. Enter again Username and Password and activate Zoiper 5!

 

Activation errors:

 "Request Timeout" →  This error indicates that firewall or proxy is blocking the connection towards our licensing server. You would need to whitelist the following IP:

185.117.83.36 on port 443 (or https://cert.zoiper.com)

 

"Forbidden" → You may see this error if firewall is blocking the connection towards our licensing server (185.117.83.36 on port 443), or when Zoiper(the user account) does not have suffcient permissions to write the 'certificate' file under:

Windows:

C:\ProgramData\Zoiper5

Mac:

~/Library/Zoiper5

Linux:

/home/YourUser/.Zoiper5

Note:

 Zoiper5 needs to sync the locally stored certificate file with our licensing server at least once each 7 days.

Usually the syncing happens during startup or once per 24 hours.

If the syncing fails the locally stored certificate will expire and you will see pop-up error notifying you.

To reactivate, simply provide internet access towards our licesning server and fill in your activation credentials.
