Setting up Springboot server with bitbucket server

[IT Dept]

Having issues when deploying an application on a server that uses springboot to pull properties from bitbucket. I am getting errors like:

o.s.c.c.s.JGitEnvironmentRepository      : Remote repository not available

or

org.eclipse.jgit.errors.TransportException: ssh://git@bitbucket01.proxibid.com:8080/prop/test3.git: reject HostKey: bitbucket01.proxibid.com

I think i have the issue narrowed down to either URI ( ssh://git@bitbucket01.proxibid.com:8080/prop/test3.git) being incorrect or an issue with known_hosts / public key of some sort?

I am using a domain authenticated service account in my application properties for the springboot server to access the repo. The service account has full permissions to the repository. I have also created known_host entries between the bitbucket server, the springboot/config server.

Thoughts?
