pytest: *FAILED* in `test_connect_basic`

### How to replicate

On macOS Tahoe 26.4, v26.04rc2, run `uv run pytest -vvvv tests/test_connection.py::test_connect_basic`

The test failed with:

```
FAILED tests/test_connection.py::test_connect_basic - AssertionError: Regex pattern did not match.
Expected regex: 'Connection establishment: Connection refused'
Actual message: "RPC call failed: method: connect, payload: {'id': '032cf15d1ad9c4a08d26eab1918f732d8ef8fdc6abb9640bf3db174372c491304e', 'host': 'localhost', 'port': 1}, error: {'code': 401, 'message': 'All addresses failed: 127.0.0.1:1: Connection establishment: Bad file descriptor. '}"
```

Same test correctly passed on Rocky Linux.
