n8n - 💡(How to fix) Fix N8N Connection Keeps Breaking [1 comments, 2 participants]

Describe the problem/error/question

What is the error message (if any)?

• error: all

TL;DR

The N8N server's repeated disconnection and reconnection may be related to its configuration or environment, and checking the server's resources and adjusting the concurrency setting could help stabilize the connection.

Guidance

• Review the server's resource utilization (e.g., CPU, memory, and network bandwidth) to ensure it can handle the current workload and concurrency setting of 20.
• Consider reducing the concurrency setting to a lower value (e.g., 5-10) to alleviate potential resource contention and observe if the disconnection issue persists.
• Verify the Docker container's configuration and ensure it is properly optimized for the N8N server's requirements.
• Check the N8N server's logs for any error messages or warnings that may indicate the root cause of the disconnection issue.

Example

No code snippet is provided as the issue is related to server configuration and environment.

Notes

The provided information suggests that the issue may be related to the server's environment or configuration, but further investigation is needed to determine the root cause. The N8N version (2.17.5) and Node.js version (24.14.1) may also be relevant factors.

Recommendation

Apply workaround: Reduce the concurrency setting to a lower value and monitor the server's behavior to determine if it stabilizes the connection. This is a safe and non-intrusive change that can help identify if resource contention is contributing to the issue.
