> only one error log was found
yes. and all error logs follows the pattern: ```failed to set server peer
[some-k8s-svc.default.svc.cluster.local:5202] err: no host allowed while
connecting to upstream```
> Please make a try with this way(only fetched the error log which contains
error word:
> ```cat logs/error.log | grep error```
```bash
bash-5.0# sed -n '/error/{s:(xx.xx.xx.xx):<my-server>:g;
s:(xx.xx.xx.xx):<my-laptop>:g; s:(real-svc-name):some-k8s-svc:g; p}'
logs/error.log # lines that match error { replace secrets and print }
