Grafana with srsRAN problem

I’m using grafana as part of srsRAN (srsRAN. It worked perfectly until I wanted to learn more about grafana. Now I get the following error:

$ sudo docker compose -f docker/docker-compose.yml up grafana

I have purged grafana and tried to remove all traces of it, but still I get the same error. The srsRAN community can’t help, so maybe someone in the grafana community has a clue?

Your Grafana container needs access to internet or at least to raw.githubusercontent.com, grafana.com, so configure that.
