License activation fails

If you try to activate a license, you might get the error code 400 and activation fails. In that case it is normally one of the following things:

  • No internet connection
  • Name server not set
  • Gateway not set
  • Date/time is not set correctly. That makes https certificates invalid preventing verification.
  • A firewall is blocking route to on port 443
