Launching of binder demo conda repository fails on mybinder.org

[gschramm]

Bug description

Launching the binder-test conda repository https://github.com/binder-examples/conda currently does not
work on mybinder.org

How to reproduce

1. Go to https://mybinder.org/
2. use https://github.com/binder-examples/conda as github URL
3. click "Launch"

Expected behaviour

docker container is built + launched. jupyter notebook interface should open

Actual behaviour

docker container is built but launch fails. Error message: "Launch attempt X failed, retrying..."
and times out after a while. (see attached screenshot)

Your personal set up

1. Tested with firefox browser on MacOS (but should not matter).
2. I can built + launch the repository offline using repo2docker

Dear @gschramm,

Thanks for the issue.

I confirm the issue on OVH server. GESIS server works as expected.
