Error message "Signature can't be started"

I am a frequent user of Docusign and it is the first time I am receiving this message after reviewing the document sent by someone for signature, initialling it, signing it and clicking on “Continue”.

I have asked the sender several times to re-send the link and the message keeps popping every time.

I have tried changing browsers and using a mobile interface… same again!

Any idea anyone?

Thanks

Laurent
