Definitely something weird going on with git cl status or something in git that it's querying for information.

'-review' is the Gerrit host suffix for anything hosted on googlesource.com. 'chromium-review' is the gerrit instance for the 'chromium' host. So the prefix will vary depending on where the code you're trying to work with is hosted.

What repository are you working in when you run git cl status?

I'm fetching from refs/remotes/origin/master (if that's what you are asking?)

No, I'm basically asking what the URL of 'origin' is, which should be the output of `git remote get-url origin`

https://chromium.googlesource.com/chromium/src.git

What is 'git config -l'?

Thanks! What branch were you working on?

when i did this i was working on captionbutton, but even on master git cl status fails. 

I discussed this on hangouts with lethalantidote@
The problem was that the remote for the "watchlist" branch was old-src, which pointed to a directory that no longer existed.
This caused git-cl not to find the git host the branch should be tracking, so it produced an empty URL, which can be seen on the error message:

Credentials for the following hosts are required:
  -review

The solution was to remove the 'old-src' origin from the repo. I will also upload a CL to provide better error messages when something like this happens.
