N8n Test Mode & Chat Trigger Not Working Properly – UI Updates Only After Refresh

I’m experiencing a serious issue with the test mode and real-time execution feedbac* in my self-hosted n8n instance. The problem occurs in multiple ways, making it difficult to work efficiently. Here’s what’s happening:

Test Mode Doesn’t Work Properly

When I launch a workflow test in n8n, nothing happens.
If I refresh the page, I suddenly see that the test actually executed.

Telegram Trigger Workflow Executes But Doesn’t Show in UI

The workflow is triggered successfully via Telegram.
I receive the message on Telegram (so the execution is happening).
However, the execution does not appear in the n8n UI unless I refresh the page.

Clicking “Stop” in Test Mode Requires Reset

If I click the Stop button while testing a workflow, the UI gets stuck.
I have to reset everything before I can run another test.

Chat Trigger Workflows Don’t Work at All

Any workflow using a Chat Trigger fails completely (it doesn’t execute).
I don’t see any logs, errors, or UI updates, it just doesn’t work.

The second picture is just an example of a basic workflow, the problem occurs on every workflow with a chat trigger

What I Have Tried: Restarted n8n and cleared browser cache.Verified that my instance is correctly configured and running.Checked WebSockets and API responses.

Hosting: DigitalOcean
Installation: Docker
n8n Version: 1.78
Reverse Proxy: Cloudflare Tunnel

Has anyone experienced something similar? Any suggestions on how to fix this issue?
