### Boost Version

```text
~# boostd --version
boostd version 2.1.1+mainnet+git.e9d18ac
```

### Describe the problem

miner restart initiated an unintended restart of boostd by systemd. Till that moment it looked fine.

After starting , UI does not appear even after a long time.

```
root@filecoin:~# ss -nalp | grep boostd
udp UNCONN 0 0 0.0.0.0:48705 0.0.0.0:* users:(("boostd",pid=941177,fd=60))
tcp LISTEN 0 4096 0.0.0.0:24001 0.0.0.0:* users:(("boostd",pid=941177,fd=32))
```

### Logging Information

```text
# boostd log list
Error: getting boost api: cannot dial address ws://127.0.0.1:8787/rpc/v0 for dial tcp 127.0.0.1:8787: connect: connection refused: dial tcp 127.0.0.1:8787: connect: connection refused```

attaching systemd's first 400 lines of log in the next section
```

### Repo Steps

systemd startup log

[start-400.log](https://github.com/filecoin-project/boost/files/13664381/start-400.log)

Start by reading the attached start-400.log and checking the boostd startup path around the failed ws://127.0.0.1:8787/rpc/v0 connection. Reproduce the systemd-initiated restart and determine whether the boost UI becomes available afterward; done means the UI is reachable after the first restart and the reported connection refusal is resolved.
