Signing Failed- There was an error processing the request, please try again.

I am having some issues with clients signing documents. The error seems to be appearing when a client forwards the document to another email and they access the link. 

The error message reads as above. When singing the document and all spaces a filled in, the error appears. 

I have tried to send a reminder, however there is another error saying a reminder cannot be sent because the document no longer requires a signature. 

Is there a way this error can be resolved?
