What happened?

I had VZ setup as per https://docs.rancherdesktop.io/how-to-guides/using-testcontainers/
and everything worked fine until few days ago when I updated macOS to Tahoe.

Now testcontainer is not able to connect to any containers

Could not connect to Ryuk at 192.168.64.2:32768

Same thing if I disable ryuk.

What works is using localhost

TESTCONTAINERS_HOST_OVERRIDE=localhost

Relevant log output
