Containers in emulated x86_64 VM become unreachable after a while (connection refused)

### Description

After switching from an Intel mac to an ARM mac, the x86_64 Colima VM sometimes ends up in a broken state, where no containers are reachable. Any requests made towards exposed ports receive "connection refused". It can only be resolved by some combination of recreating the VM and rebooting my mac. Restarting the containers or the VM has no effect.

### Output of `colima status`

```
colima status
INFO[0000] colima is running using macOS Virtualization.Framework
INFO[0000] arch: aarch64
INFO[0000] runtime: docker

```
colima status x86

```

### Reproduction Steps

1. I'm running two VMs, one aarch64 and one x86_64. These are created using `colima start --cpu 4 --memory 16 --disk 100` and `colima start --cpu 2 --memory 8 --disk 75 --profile x86 --arch x86_64`, respectively.
2. At first, everything works as expected. I switch between docker contexts and start and stop services in both VMs using docker compose.
3. After some hours/days, the containers in the x86_64 VM stop responding to network requests. I can stop them and start them without issue. Their logs contain no errors. However, they cannot be reached. To test this: `docker run -p 8080:80 nginx`, then `telnet localhost 8080` should answer "Connected to localhost", however answers "Connection refused".

### Expected behaviour

Expect that healthy containers are reachable.

### Additional context

I appreciate any help towards how I can debug this and provide further information.
