Stuck waiting for ssh -- tcpproxy no route

### Description

Hello,

I'd been working with a VM and then lost access to it. Doing `limactl stop && limactl start ` didn't seem to help, and now it just gets stuck indefinitely `Waiting for the essential requirement 1 of 3: "ssh"`.

Interestingly, this line repeats:

```
INFO[0004] [hostagent] 2023/01/11 21:51:42 tcpproxy: for incoming conn 127.0.0.1:52962, error dialing "192.168.5.15:22": connect tcp 192.168.5.15:22: no route
```

Which seems to me like maybe there's a problem with the bridge interface.

The VM template I'm using looks like this:

```
# experimental settings
vmType: vz
mountType: virtiofs
networks:
- vzNAT: true

# make it a native M1 VM
arch: aarch64

# appropriate levels for the host machine
cpus: 8
memory: 16GiB
disk: 300GiB

...

# share a temp space to make sharing files with the host easier
mounts:
- location: "~"
- location: "/tmp/lima"
writable: true

ssh:
localPort: 60023
forwardAgent: true
```

Logs look like this:
