Problem:

Failed to update VXDIAG VCX SE Benz license. Error: Update License failed. Retry. Error info 4003. Received invalid data from server. Any solution?

Solution:

1. Change WiFi hotspot then update license again.

2.If still have this error using WiFi hotspot, send device S/N to vxdiagshop.com engineer to check your license status manually.

Then change another wifi hotspot, update VCI firmware and then update license.
