I run Home Assistant with Docker and I have run into an issue that I don’t know how to resolve.
The problem is that the container cannot access the internet. I confirmed this my getting into the container and pining google.com. Therefore, no cloud-based integration works.
Everything worked fine until a couple of weeks ago. I restarted my server and then this problem started. Sometimes after a couple of days, for no apparent reason, the container re-gains access to the internet.
