Issue Description

Random 504 Gateway timeout when downloading dependencies. This fails about 50% of our Android builds at the moment.

Note: Bintray has been showing green status last 7 days, so I don't think it's an issue on bintray side.

Closing this as not seen the issue last 2 days, so it was probably an intermittent issue.

I've been seeing this over the past few days. Can't get it to succeed today, always getting a 504. Works fine on my network, just not in azure.

We saw this again on Thursday 4th June, then it was fine again on Friday 5th June.
