Can't push to remote branch, cannot be resolved to branch

Question

I migrated my repos from Bitbucket or Github. I don\'t think this matters but it\'s the only thing different... For a little while I had two remotes set up:

Answer 1

For my case, I used to have branch folder (or whatever it is called) with capital letters, then I create a new one with difference casing (lowercase) but git actually create the branch with capital.

I have created a branch like feature-ABC/branch1 before and pushed it. Then I create a branch feature-abc/branch2 (notice the lower-case ABC), and try to push it to remote using git push --set-upstream origin feature-abc/branch2 and get the 'cannot be resolved to branch' error. So I git branch and see that it actually created feature-ABC/branch2 instead of feature-abc/branch1 for me. I checkout again with git checkout feature-ABC/feature2 and push it using the uppercase (feature-ABC/feature2) to solve it.
