Why Does My Triggered Workflow Experience a Redis Connection Timeout?

I created a workflow that uses redis, and it works perfectly when tested with mock data; however, when executed as a triggered workflow, it times out when connecting to redis.
Below is the error message I receive:
JAVASCRIPTError: Connection timeout at Socket.<anonymous> (/usr/local/lib/node_modules/n8n/node_modules/n8n-nodes-base/node_modules/@redis/client/dist/lib/client/socket.js:177:124) at Object.onceWrapper (node:events:632:28) at Socket.emit (node:events:518:28) at Socket.emit (node:domain:489:12) at Socket._onTimeout (node:net:595:8) at listOnTimeout (node:internal/timers:581:17) at processTimers (node:internal/timers:519:7)
The beginning of my triggered workflow contains the start node and a subsequent Get Key node for redis.
My n8n setup is as follows:
- n8n version: 1.73.1 (Self Hosted)
- Database (default: SQLite): sqlite
- n8n EXECUTIONS_PROCESS setting: own, main
- Running n8n via: docker
- Operating system: macOS 15.2
Any insight into why the workflow times out during a triggered execution would be greatly appreciated.

Based on the error message and your setup details, the most common culprit in this scenario is that the Docker container's network configuration is preventing it from connecting to your Redis server during a triggered run.
Here are a few things to check:
-
Redis Hostname & Network Configuration:
- If you’re using “localhost” in your Redis credentials, note that when n8n runs inside Docker, “localhost” refers to the container itself—not your host machine.
- On Docker for Mac, you might instead need to use the hostname “host.docker.internal” for your Redis host, so that the container can properly reach the Redis instance running on your macOS.
-
Credentials Consistency:
- Double-check that the credentials used during your test execution are the same as those applied when triggering the workflow. Sometimes testing with mock data may bypass certain network layers or credential issues that become evident upon actual triggering.
-
Network Connectivity from Docker Container:
- Verify that the Docker container running n8n can access the Redis server. You can try connecting to Redis from within the container using a simple client (or by executing a command inside the container) to rule out any connection issues.
-
Timeout Settings:
- While the error points to a network timeout, ensuring that your Redis server isn’t overloaded or delaying responses can also help. Look into whether any firewall or security rules might be affecting connections between the container and the Redis server.
By going through these steps, you can isolate whether it’s a matter of modifying the host address in your Redis credentials or an underlying networking issue between your Docker container and your Redis instance. Adjusting the host from “localhost” to “host.docker.internal” (if applicable) is often the first change that resolves such timeouts.
