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.
  • Wrong license. If you buy Repetier-Server Upgrade (OEM to Pro), you can only upgrade Repetier-Server OEM. This will not work with Repetier-Serfer Free.
  • Spelling error. I and 1 and O and 0 can quickly be mixed up. Copy & past is always safest.
  • 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 license.internetloesungen.com on port 443.
