Site scanner error

Hello,

I just enabled the Site scanner a couple of days ago and I’m getting this same error every day:

Error Message: Unable to determine if the scan target is allowed: Could not verify keypair: Jeton expiré. (itsec-opaque-token-expired).

Error Code: site_verification_failed.response_error

If you contact support about this error, please provide the following debug details:

Array
    code   => site_verification_failed.response_error
    data   => Array
        url   => https://mywebsite.com

Should I check something in particular?

Thanks.
