Error Activating CB Drive after upgrade to v.2.4.3.15

After upgrading from v.2.4.2.16 to v.2.4.3.15 I am not able to re-activate the product.
Why I need to activate it again since it was active before the upgrade?

The error was:
“The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel”

Details show:
“The remote certificate is invalid according to the validation procedure.”

[reply=“ACA;1002”] Hello, this is definitely something strange happening. I would suggest sending us the logs to investigate why it might be happening. Just right-click the Drive tray icon and choose Diagnostic, please mention for Sergey N. in the description so i can identify it. Thank you

It might be related to the AWS instance ENA driver/network setup.
I will open a support ticket [reply=“Sergey N;1019”] .
