Workflows not responding

Questions

Hey everyone :waving_hand:

I’m running a self-hosted version of n8n on a VPS and ran into a strange issue a couple of days ago. Hoping someone here might have an idea what’s going on :folded_hands:

The problem: My workflows have stopped responding to external input like:

  • Form inputs (via “On Form Submission” node and regular “Form” nodes)
  • Webhooks
  • Telegram Approval buttons.

These workflows have been working perfectly fine in the past.

But now, here’s what happens:

  • When I submit a form (using the “On Form Submission” trigger), I can see the workflow execution start in the executions list. But it just hangs on the next Form node and never proceeds. I have to manually stop it.
  • Telegram workflows still send out the message and show the usual buttons. The button click triggers the expected pop-up in Telegram. But after clicking “Yes” or “No”, the follow-up website just spins forever and never loads.
    Everything else in n8n works just fine. I can access the UI, create and edit workflows, etc.

My Setup details:

  • Self-hosted n8n on a VPS via Docker on Ubuntu
  • Problem occurred on version 1.99.1. Update (1.100.1) didn’t help
  • Database: PostgreSQL
  • n8n EXECUTION_PROCESS: default
  • Accessed via Cloudflare (maybe relevant?)

Has anyone experienced something similar? Any idea what might be causing this or where to look?

Thanks in advance for any ideas or pointers! :raising_hands:

Hi there, I think cloudflare is the problem (maybe).
I experienced similar issues with yours, and yep. I have no idea what is going on…
But… have you tried to change n8n execution_process to queue? Maybe it will help.

Or maybe you weren’t activated the workflow?
