this was with the previous address (just moved the repo). I think you have to use the token of the remote you are pushing to (e.g. pandas-dev/pandas-docs-travis), and not where you are pushing from I think I have to update `ci/build_docs.sh` to use the new address. Let me try that (just pushing to master). I moved the docs back for now. But, anyhow, the authentication was still failing ...
