Im having some issues attempting to login using PartnerConnection via a simple Java project, my SF org has the below URL structure:

https://[myorg].lightning.force.com/services/Soap/u/34.0/[orgid]

(tried with multiple api versions)

when ever i run the project im seeing the below error that appreas to be triggerd during the  setting of PartnerConnection to a new connection.

Does anyone have any ideas what could be the issue here?
