[Bug] SSH authentication failing or access restrictions preventing VPS login

### Bug Description
I am attempting to use Claude Code to log into my own VPS, but the system is blocking the connection due to automated restrictions or safety guidelines. Since this is my personal server, I need to bypass these restrictions to manage my environment. Please assist in resolving this access block.

### Environment Info
* **Platform:** Linux
* **Terminal:** PyCharm
* **Version:** 2.1.241
* **Feedback ID:** `8b66c161-7962-4275-8ba4-fc882ce44e10`

### Errors
```json
[]
```

The report names no repository files, tests, or reproducible error. Start by reproducing the SSH login attempt and collecting the actual restriction or authentication output; done would require a specific failure with verified login behavior after the relevant issue is identified.
