Connection problems from Eclipse to GitHub

I have been trying for days to connect successfully to my repository from Eclipse.

My error always seems to be:

Can’t connect to any repository: GitHub - jechild1/TestJavaProject ( Missing tree 368a6929aa4c30a802d7106d90c75d192eef7e17)

This always happens when pushing. I’ve tried normal username / pass, SSH, and the token. Nothing seems to work. It will connect enough to see the branches, but pushes always fail.

Added a few screenshots to aid in understanding. Help!
