Conection Lost 1.95.2

Bug Description

Bug Report: Intermittent "Connection lost" errors in n8n v1.95.2

Describe the bug

I am experiencing frequent and intermittent "Connection lost" errors while using n8n version 1.95.2. This issue occurs randomly and makes it very difficult to work on workflows.

Impact

This issue is significantly impacting productivity by:

• Preventing the saving of work, leading to potential data loss.
• Making it difficult to activate or deactivate workflows reliably.
• Causing frustration and delays in workflow development and management.

To Reproduce

Steps to reproduce

It's hard to provide exact steps to reproduce due to the intermittent nature of the bug. However, the "Connection lost" error typically appears when:

1. Editing nodes within a workflow.
2. Attempting to save a workflow.
3. Trying to activate or deactivate a workflow.
4. Navigating between different workflows or an n8n sections.
   The connection will drop and then usually reconnect after a few moments, but the interruption is disruptive.

Expected behavior

Actual behavior

The n8n interface frequently displays a "Connection lost" message (similar to the attached image, though the image shows a generic connection lost message, the in-app n8n message is specific to the UI). This prevents saving changes, activating/deactivating workflows, and generally disrupts the workflow editing process. This requires frequent manual retries to save or activate, significantly slowing down development and operations.

Hi, I updated to 1.95.2 recently (10mins ago) and now I got the issue of a lost connection.
Self hosted N8N on hetzner with coolify. Docker and overall health check is ok. Log tells: .. " expecting wss:// ... "
Backend in N8n is working, but all workflows are broken at the moment with the message:

Any news on this?
Thanks

How can I downgrade to a working version? Currently, the Docker Compose file uses image: docker.n8n.io/n8nio/n8n.

I'm experiencing the issue with Traefik. Will switching to Nginx or Caddy solve the problem?
