## TL;DR
A VPG in error state after a host disconnect needs the replication path re-established, not just time: check the host's connection state in Zerto, the VRA on that host, and whether the VPG is waiting on a resync that cannot start. Reconnect or restart the affected VRA, watch the VPG leave the error state into sync, and confirm its recovery point objective returns inside the SLA before closing the incident.

```text
Zerto replication failed "VPG is in error state" after host disconnect
```

## Use this when
- The job or restore fails with this symptom: Zerto replication failed with VPG is in error state after a host disconnect.
- You are working on a Zerto VPG protecting VMs on a host that disconnected and the failure repeats on the same target or schedule.
- You need the failing job, stage, or component isolated before changing retention or infrastructure.

## Not for this skill when
- A VPG in error because its journal or target datastore filled, where the host disconnect was coincidence and the fix is storage.
- The error text names a different product, stage, or root cause. Match the verbatim error first and use that skill.

## Steps
1. Open the VPG's detailed status and read the specific error and the components it names. Verify: the VPG's own diagnosis is recorded
2. Check the disconnected host's state and its VRA: running, responsive, and connected to the Zerto manager. Verify: host and VRA health are established
3. Restore the connection or restart the VRA, then watch the VPG transition from error to syncing. Verify: replication resumes visibly
4. Confirm the VPG reaches its target RPO and note the data gap window the disconnect created. Verify: RPO is back inside SLA with the gap documented

## Variant phrasings
### zerto vpg is in error state host disconnect
The verbatim phrasing.
### zerto replication failed vpg error vra reconnect fix
The VRA phrasing.
### zerto vpg error after host disconnect resync rpo
The resync phrasing.

Compatibility: Zerto virtual protection groups and host connectivity

## Why it happens
Zerto's continuous replication depends on per-host components staying connected, so a host event puts its VPGs into error even though the VMs themselves are healthy. The error state is a container for several causes, and the VPG's detail separates a connectivity problem from journal or storage problems wearing the same label.

## Edge cases / pitfalls
- Multiple VPGs erroring together points above the host, at the manager or the network between sites.
- A VPG stuck in error after connectivity returns may need its sync restarted from the VPG's own controls; do not delete and recreate as a first move.
