Improve error message when topology service is down
The following discussion from !3820 (merged) should be addressed:
-
@kkloss started a discussion: suggestion (non-blocking): when the topology service is not up (be it because it had a slow start or because of an error), the HTTP router will show a “Network connection lost.” error.
It’s fine for now but let’s improve the error message in a follow-up to something like “Could not connect to the topology service. Check that it is running, for example try
gdk status gitlab-topology-service
.”
