Git push not working but git pull does work on remote branch

I had a similar problem using an old version of git

try

git version

and compare with someone who is not having the issue

Although, here it looks like the problem is that you don't have a local REF for pushing that branch back to the origin.

Does this work? It explicitly indicates which branch to push to (and from)

git push origin workflowNewCOBRequest1:workflowNewCOBRequest1
