Definitely concerned about the errors connecting to from querier → query-frontend. Tempo would be unable to answer any queries if this connection didn’t work.
We recently added the ability to just dump every trace that gets into Tempo. Perhaps this could help:
This is the address the field that has to be set correctly for the querier to connect to the frontend. You could double check this as well as exec into your querier pod and see if you can connect to the frontend.

frontend_worker:
frontend_address: ???
