fetching is not cancable/waits "forever"

started up, took a long time for central to show up (as if it was waiting for something to timeout)

Then gets stuck in refreshing examples - cannot cancel it nor will it stop when closing central.

here is the stacktrace it was "locked" at.

at same time m2e index was downloading causing some slowness - not sure if related.
