Creo license problem

Hello

I've been using Creo on my personal computer for a little over a year, I've been using my orange 4g connection, nevertheless since the beginning of the confinement the software keeps telling me that I have a license problem (knowing that before the confinement it happened to me from time to time but it was enough to wait 5 minutes for me to use the software), I suspect the reduction in internet speed to be a cause of the problem. Do you have any ideas to solve this problem? 

Thank you
