Tour NetworkError on Firefox

Moved from GitHub tutorial/94

Posted by dimm0:

Steps to reproduce the issue (command/config used to run Dgraph).

Follow the tour guide. It breaks on step 4 with:

TypeError: NetworkError when attempting to fetch resource.

Previous steps work fine.

Expected behaviour and actual result.

Tour works as intended

Please share the link to the step that’s breaking, and information about your setup (operating system, web browser and version).

Thanks for the info, @dimm0. I can also reproduce the issue on Firefox. For now, you can use Chrome for the Tour.

This problem is specific to firefox because it blocks HTTPS tour from talking to HTTP localhost. Needs a workaround or at the very least a warning for users.

Note that Safari is affected as well.

Have had the same issue on Safari at every step. If I click back to the previous section, then click forward again, it works on the second attempt.
