Licence expired notification when license is still valid

Since this week, I am getting an “licensed expired” notification but I do have a valid license.

Activate the same license again. It’s probably false negative during interrupted license check.

I have the same problem and when I try to reuse my license again I get the following error:

Failed to update the license file: unexpected end of JSON input

Most likely you have a firewall blocking the connection to our license server at (which is hosted on Google App Engine).
