Docker for mac: Connection timeout

General
1

I see a lot of discussion of “Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)” but none of the responses seems germane.

I am using MacOS Big Sur on an Intel mac. I can use ‘curl’ at the command line to fetch https://registry-1.docker.io/, but docker itself cannot.

Playing with resolv.conf makes no sense since MacOS doesn’t use that file.

I have an MDM that turns on the MacOS firewall and cannot change that. Still, the firewall configuration is fairly permissive - among other things, signed software is allowed to receive incoming connections.

Never mind. This was because I turned on the experimental virtualization feature. That seems broken ATM.

Same problem here.
If I turn on the new virtualization framework, I can’t pull images.

Same here. Thank you for catching that!
