Describe the problem/error/question

Hello!

I have the same issue as Workflow Editor Blank (White) After Upgrading - #22 by thefourCraft and here hhttps://community.n8n.io/t/workflow-editor-blank-white-after-upgrading/11310/5

And all actions is that topics didnt help me. Different browser and incognito mode also didnt help.

I have self-hosted n8n version (tried latest n8n and n8n langchain beta. The problem is that workflow editor is blank (white). I am using traefik.

docker-compose.yml here: N8N Traefik Blank Page Error - Pastebin.com

and env var WEBHOOK_TUNNEL_URL=https://n8n.domain.com

Everything works properly with localhost:5678 but it is white page with n8n.domain.com

Please help me, how can I solve this issue and access with n8n.domain.com? And after that I want to configure webhook url for telegram and other webhooks.

Hey @Embody,

Welcome to the community :cake:

It sounds like there is probably an issue in your configuration, I would start with a smaller install and not jump to queue mode until you need it that way you can add options to see if it impacts anything. I would also start with a configuration that is known to work like the one we document here: Docker Compose | n8n Docs
