All my containers inside Portainer stopped working right after the Portainer update. I can’t ping 8.8.8.8 from inside any container, and internal DNS resolution is completely broken, containers can’t resolve each other’s names, and I can’t even ping other containers directly.
Before anyone asks, the answer is yes. I have already restarted Umbrel several times.
For those encountering the same issue, I managed to resolve the issue by purging the Docker image and subsequently redeploying the container.
Unfortunatelly it didn’t solve the problem. I am still with problems.
