Currently I cannot login to my local Bitbucket Server on Sourcetree 2.5.5.

1. Select Remote (with the cloud icon) in the header
2. Select Add Account button
3. Select Bitbucket Server from the Hosting Service picklist
4. Input my server's URL, which uses a proxy
   • I've tried using the proxy URL and non-proxy with port URL
   • With and without https & http in the URL
   • I've even tried using a SSH key that I generated and added to my Bitbucket profile solely to troubleshoot this issue. That failed as well.
5. Preferred Protocol and Authentication are limited to 1 choice each (HTTPS and Basic respectively)
6. Input my Username (My account is an system admin and admin for the project I'm wanting to clone)
7. Upon inputting my Username, the application attempts to connect. I receive the following error:

At this point, I'm dead in the water. I need direction here. I either receive assistance from you fine folks that built & support the application, or I use another application all together.
