How to Fix the nextcloud-talk EADDRINUSE Crash Loop

What's Happening

You're seeing an EADDRINUSE: address already in use 0.0.0.0:8788 error in your OpenClaw logs. Your gateway service is caught in an infinite restart loop: it starts the webhook server, thinks it failed, triggers an auto-restart, and immediately crashes because the port is still held by the first instance. This affects versions 2026.2.17 through at least 2026.2.24.

The Fix

There is no official patch for this in the latest versions yet. The most stable fix identified by the community is to roll back to a known-working version.

Run the following command in your terminal:

openclaw update --tag v2026.2.15

If you are running inside Docker or a systemd environment, restart your container or service after applying the downgrade to ensure the process memory is fully cleared.

Why This Occurs

The plugin's startAccount function is broken. It resolves the internal promise before the webhook HTTP server is actually ready or while it is still settling. The OpenClaw gateway framework sees the resolved promise and erroneously assumes the channel has exited, so it initiates an automatic restart sequence (usually after 5 seconds). During this restart, the original process hasn't finished releasing the socket, leading to the EADDRINUSE exception. This same behavior is triggered by SIGUSR1 signals, making live configuration reloads impossible.

Prevention

Keep an eye on GitHub issue #19854. Avoid updating to any release newer than 2026.2.15 until the fix involving proper promise lifecycle management is merged. If you require the latest version for other features, you are currently blocked until the maintainers refactor the channel lifecycle manager to account for the webhook server's binding state.
