Container seems can't reach internet

Grafana Configuration
1

Hello all,

I’ve installed Grafana via Docker Compose in fresh RPi5 Bookworm with no firewall. The installation went smoothly and I’m able to open and login to the UI. But for some reason when I tried to import dashboard using the ID, the UI crashed. Log shows that it can’t reach internet and I dont why.

Spend two days trying to fix this but was to no avail. Do I have wrong configuration?
Just clarify, I do have other containers that can connect to internet.
