MYSQL connector "breaking" after some time

  • n8n version: 1.18
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): docker
  • Operating system: Ubuntu


I have several workflows querying my MYSQL database.

After a few days I start to get repeated “ERROR: connect ETIMEDOUT”.

Restarting the MYSQL database and/or server does not fix the issue… Restarting N8N does.

So obviously the error is in N8N.

Can I report it as a bug?



Hey @xewonder,

Can you update your n8n instance and let me know if that helps? There was an issue where we were not closing the connections properly and I suspect the error you are seeing is related to that.
