@qdm12 commented on GitHub (Jan 21, 2021):

I think your internet connectivity is down for the container for some reason. The initial connectivity checks trying to access google.com fail as well.

You can always set the dns with docker-compose, for example:

dns:
  - 1.1.1.1

But that's irrelevant to the container really. Maybe check your firewall as well? Closing the issue for now but feel free to comment back.
