New motherboard, Trados asks Activation code

Hello, I have replaced my motherboard and now Trados asks for Activation code. I have tried to used the code that's in my account under "License and Subscription" but the software returns a "Activation failed. Could not connect to the activation server. Check the activation server address in the provider setting Could not create SSL/TLS secure channel". Tried also to deactivate to no avail. Not sure what to do and I have of course stringent deadlines.
I run Trados Studio 2019 Freelance Plus 15.2.8.3007.
Please advise.

Gianni
