I have problems with an Approval workflow ( in the workflow I use the "Request approval" action).  2 weeks before it works fine. But now I get an error , nothing were changed. The Domain user has no access to the workflow task. If he click in the approval message on the link to approve ,he got a message in Internet Explorer:

"Sorry, you have no acess to this site."

URL: sharepointserver/sites/sitename/Workflows/_layouts/15/AccessDenied.aspx.....

 

all Domain User have "Edit" "Contribute" and Approval permission in the Form Library and for the Workflow Task list.

I have no idea what's going wrong.

 

This is the error in the ULS LOG
