Error: Unsuccessful - The underlying connection was closed: The connection was closed unexpectedly.

If you test the connection and get this error, add the following content into the Custom Request Headers field:

user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.119 Safari/537.36

Error: Writeback failing with 401 error

This means that we do not have the proper authentication to update your orders. Try ticking the "Use consumer key and secret as query string parameters" option. This usually bypasses many of the security/firewall issues a server may be having with processing the authorisation 

Error: Writeback failing with 403 error

This means we do not have the proper permissions to update your orders in your store. Make sure the API key has both read and write permissions. 

Also ensure that the user you have assigned is a stand alone user with admin permissions.
