EngineIO read error after some days of uptime

I'm running the latest v2 version.
On all of my hosts, after some days of uptime, I see this in the logs:
```
2025-12-19 15:02:33.130 [autokuma::sync] WARN: Encountered error during sync: Error during communication: EngineIO Error
```

And it won't sync with uptime kuma at all.
