Impossible to connect to Jetpack

Hello !

I just made a migration from a staging site to my real site. Jetpack works on the staging site but impossible to connect it on the new in production website.
When I click on “Connect Jetpack”, I got the following error message :

“Invalid request, please go back and try again.
Error Code: invalid_request
Error Message: The URL stored by the Jetpack servers does not match your site. Please try disabling the Jetpack plugin, re-enable it, then connect again”

But I cannot disabling jetpack, it seems to be included with my plan.

Can you please help ? Thanks a lot !
