Error : The string did not match the expect

I have installed wordpress 5.0 and jetpack doesn’t work at all anymore.

I’m still not able to load your site and I tried several different locations around the world.

Please let me know when your site is back online so I can have a look.

Did you try with the good url ?
Because there is no problem yesterday or today : the site is online !

I’m sorry. I was using the URL you previously shared. The one with the dot. Now I’m able to load your site and I see that Jetpack is installed and properly connected to WordPress.com.

I noticed that you have a lot of plugins installed. Can you please deactivate your plugins and see if Jetpack works? There are several plugins that replicate Jetpack’s features and this may cause conflicts.

Hello,
I have already done this in the past with the same issues.
I will do a test again later.

Please report back letting us know if that makes any difference.

I have this error with or without plugins active :
“Details d’erreur: The Jetpack server was unable to communicate with your site https://chti-sportif.fr [IXR -32300: transport error: http_request_failed cURL error 28: Connection timed out after 10001 milliseconds]”

Now our debugger shows a problem with the security token on your site:

https://jetpack.com/support/debug/?url=https%3A%2F%2Fchti-sportif.fr%2F

Please disconnect and reconnect Jetpack, and if that doens’t work, please open a support ticket at https://jetpack.com/contact-support/?rel=support for further help with this. Please include a link to this forum thread when you do that.

I have reconnected the site with wordpresss.com but still have some issues with jetpack settings.
I have sent an email to support ticket

Thank you for submitting a ticket. Due to the holidays it might take a little longer than usual before someone can reply, but we’ll get to it as soon as we can.
