Just tried this at university and interestingly all fig functionality is blocked when using the university's wifi, probably due to the proxies they have in place, while hot-spotting from my phone over 4g seems to work fine.
edit:
after switching back to university wifi fig also worked fine, so it may be an issue with the wifi or there may be a need to refresh the network connection when trying to set everything up
