Arc/ git not behaving as expected

I’m trying to submit code for review using ‘arc diff’, and after approval use ‘arc land’ to accept revisions and push changes to remote git server. arc is behaving weirdly, looks like ‘arc land’ completes successfully, but it silently fails in the background and doesn’t push my changes to the remote server, and none of my team can access code changes I’m making.
ark land is successful even get the notice that it is- and it doesn’t. the arc list shows the differential still there, and nothing is pushed to git

Can you run arc land --trace and post the output?
