Jetpack and Google Analytics stats are different

Hello everybody,

For several months, Jetpack statistics have been two to three times lower in terms of visits to my site compared to Google Analytics statistics.
I would like to know if you have the same problem as me or not.
The changes I made over the last few weeks is the addition of Complianz for cookies in order to comply with the GDPR in the European Union. I also have the nitropack extension to speed up my site but I have always had it and before, I had no problem even with the extension installed.

Can you help me ? Here is my website: https://3dcreation.fr/

Here are the jetpack stats: https://ibb.co/jh64Rt6
Here are the statistics from Google Analytics: https://ibb.co/Gxzpr1Y

Have a good day,
Sincerely.
