[Bug]: After Valheim Update LGSM 'monitor' command no longer able to detect if Valheim is up

### User story

As a Server Admin, I want LinuxGSM 'monitor' command to detect that Valheim is down and restart Valheim so that I can maintain a high SLA

### Game

Valheim

### Linux distro

Debian 12

### Command

command: monitor

### Further information

```bash
vhserver@valheim:~$ ./vhserver monitor
[ OK ] Monitoring vhserver: Checking session ... OK
[ FAIL ] Monitoring vhserver: Querying port: gsquery: 127.0.0.1:2457 : 60/5 ... FAIL
[ OK ] Monitoring vhserver: Sending Discord alert
[ OK ] Stopping vhserver: Graceful: CTRL+c: 4 ... OK
[ OK ] Starting vhserver: The Royal Refuge
```

### Relevant log output

```shell

```

### Steps to reproduce

1. Run ./vhserver monitor

Start by reproducing the issue with ./vhserver monitor on the stated Valheim and Debian 12 setup, then inspect the monitor output around gsquery and port 2457. Done means the monitor command correctly detects whether Valheim is running and restarts it when it is down.
