Create issue TFS 2017

Hi All,

Apologies if this has already been asked (I have had a search and found nothing) but are there any issues with Create Issue and TFS 2017?

Regardless of our configuration, we get the message:

Unable to create item. Reason(s):

Unable to find the connection.

In connection manager, the connection is successful and the template is valid, is there something I am missing?

TIA

Morty
