Problem:
When you activate your license you may get the below error
ActivationFailed: The underlying connection was closed:
An unexpected error occurred on a send.
Possible Cause:
You may be running an old version of ZappySys Product. The old version was using TLS 1.0 for HTTPS communication during license activation. TLS 1.0 is now deprecated and many servers may block traffic if it's using TLS 1.0.
Solution:
Use the latest version of ZappySys Product if you get this error. License Manager in the new version is using TLS 1.2 by default rather than TLS 1.0.
Download New version > Uninstall old version > Install New version.

After installing the new version you may see License Manager with a new look. Make sure it shows ONLINE status before you attempt to activate again.
If the status is showing OFFLINE in that case you need to generate the offline license key.
