I initially started looking into this when some users were complaining about installing rubygems via bundle install returning no data, but in looking through the logs I’m seeing similar errors for a nuget repository and a pypi repository.
We’re running version 3.30.0-01 behind nginx as a proxy, closely matching the recommended nginx config. Here’s an example rubygems error:
