Hey a few questions:

  • have you previously installed Deepseek community nodes?
  • have you tried re-creating the credentials from scratch?
  • have you tried testing in a fresh workflow? (with the new creds)
  • have you recently upgraded n8n versions?
  • in your Network dev tools tab, can you check to what endpoint the request is going to?

  • Deepseek community node installed (n8n-nodes-deepseek v1.0.6)
  • I created new credentials and it happens in both
  • Yes, tried in multiple workflows
  • I’m in the latest version - it’s the first time I try to run it (new with n8n…)
  • Didn’t succeed to see any endpoint…

Just to emphasize - HttpRequest node with same credentials - no problem and call succeeds

There are reports in Github of people that previously installed the deepseek community node, later upgraded and started using the new built-in deepseek node.

You could try:

  • removing the community node and restarting
  • removing and updating n8n
  • clean install

to eliminate any potential clashes there. Let me know if any of this you can do and if it helps.

I removed the community node and it’s working now! amazing :slight_smile:
So I don’t need the community node at all?
