Question: Why is the OpenClaw gateway failing to start after the config fix, and how do I resolve the “Signal plugin missing” and “Unrecognized keys” errors?

Answer: It appears that after resolving the legacy allowPrivateNetwork issue, the gateway is hitting a second-stage validation failure. This is common in the 2026.4.5 build where strict schema validation was introduced for all channels.

1. Fix the “Signal” Plugin Error

The log [plugins] signal missing register/activate export indicates that the Signal plugin is either corrupted or its entry point has changed in the latest update.

The Cause: OpenClaw 2026.x requires plugins to export specific lifecycle hooks (register and activate). If you are using an older version of the Signal plugin, it will fail validation and stop the gateway.
The Fix: Force a reinstall of the Signal plugin to fetch the compatible version:
```
  openclaw plugins install @openclaw/signal@latest
```
If the error persists, run openclaw plugins list as suggested in your logs to see if it is flagged as “Incompatible”.

2. Resolve “Unrecognized Keys” in Nextcloud-Talk

The error Unrecognized keys: "enabled", "baseUrl", etc. occurs because the Nextcloud-Talk configuration structure was moved into a sub-object or changed to a plugin-based schema in the new version. The gateway no longer recognizes these keys at the top level of channels.nextcloud-talk.

Check your ~/.openclaw/openclaw.json and ensure it follows this updated structure:

Old Key	New Location/Key
`enabled`	Moved to `plugins.allow` (add `"nextcloud-talk"` there)
`baseUrl`	`channels.nextcloud-talk.account.baseUrl`
`botSecret`	`channels.nextcloud-talk.account.botSecret`
`network`	`channels.nextcloud-talk.network` (Ensure it is an object, not a string)

Corrected Configuration Example:

"channels": {
  "nextcloud-talk": {
    "account": {
      "baseUrl": "https://your-nextcloud-instance.com",
      "botSecret": "your_secret_here"
    },
    "rooms": ["room_id_1"],
    "network": {
       "dangerouslyAllowPrivateNetwork": true
    }
  }
}

3. Final Verification

After making these changes, clear the temporary runtime state and restart:

Clear logs/state: rm -rf /tmp/openclaw/*
Repair any remaining syntax: openclaw doctor --fix
Start the gateway: openclaw gateway restart

If it still fails, check the detailed logs using the command provided in your terminal output: journalctl --user -u openclaw-gateway.service -n 50 --no-pager
