On one of the lab boxes, the telemetry streams were not getting through -- neither on new connections, nor on the old ones. This is how the logs looked like:

I have not tried fetching other data besides the telemetry stream :(.
Stuff was fixed by restarting the reverse proxy (which took ages to finish):
