Server error we're working to resolve an issue that prevents us from completing your request. try again later. (-6)

Just bought a key and updated the product, got this blocking screen message "server error we're working to resolve an issue that prevents us from completing your request. try again later. (-6)" while trying to activate.


Does any one have any idea how can fix it?

 

thanks for your attention

 

PS saw older post where some fixes worked for some user and not for all, of course I already run RnR and restarted a few time.
