# Self-Healing CI: Recovering a Transient SSH Connection Drop

> An SSH connection that drops mid-step is a transient network problem, not an auth or host bug. See the manual fix and how self-healing CI reconnects and retries.

An SSH session that drops mid-command is a network blip, not a rejected login -- reconnecting and re-running the command clears it.

## What makes a failure safely retryable

Automatic retry is only correct for failures that are genuinely transient. Retrying a deterministic failure wastes minutes and hides a real defect, so the classification matters more than the retry mechanism.

- Safe to retry: network timeouts, registry 5xx, transient DNS failures, a service container that was not ready, a spot instance reclaimed mid-run.
- Not safe to retry: assertion failures, compile errors, lint violations, anything that fails identically on every attempt.
- Ambiguous, and worth investigating rather than retrying: out-of-memory kills, disk exhaustion, and flaky tests. These repeat under load and a retry only hides the trend.
- Always record that a retry happened. A pipeline that silently retries is a pipeline whose real failure rate you do not know.

## FAQ

### What causes Self-Healing CI: recovering a transient SSH connection drop?

A step that runs commands over SSH (a deploy, a remote build, an rsync) fails with a dropped connection -- broken pipe, Connection reset by peer, or Connection closed by remote host. The host, key, and command are all valid; the session was cut by a transient network problem. A human re-runs the job and the SSH step completes unchanged.

### How do I fix Self-Healing CI: recovering a transient SSH connection drop manually?

[object Object]

### Can Self-Healing CI: recovering a transient SSH connection drop be fixed automatically?

A dropped SSH connection has a recognizable transient signature -- a reset or closed session rather than an auth rejection -- and the safe response is to reconnect and retry. A self-healing CI pipeline detects the connection drop, retries with backoff, and only escalates if the host is genuinely unreachable or authentication fails, so a
