My N8N deployment is inaccessible after setup

[Kinlon_Jiang]

Describe the problem/error/question

I deployed n8n on my CentOS server and accessed it via the ip:5678 port.

On January 8th, I was able to access it successfully using this method. However, I forgot the password later on.

On January 17th, I deleted the volume and reinstalled n8n, but I can no longer load the page via ip:5678. In the browser’s console, I noticed some error messages. How can I resolve this issue?

What is the error message (if any)?

Try these (in the same order)

1. Check the protocol (use HTTPS):

   • Ensure n8n is running behind an HTTPS proxy (e.g., Nginx)
   • Set up a SSL certificate or configure your reverse proxy accordingly.

2. Fix Cross-Origin-Opener-Policy Header:

   • Update your reverse proxy configuration to include the correct Cross-Origin-Opener-Policy header:

     add_header Cross-Origin-Opener-Policy same-origin always;
     add_header Cross-Origin-Embedder-Policy require-corp always;
     

3. Update your browser/environment:

   • The crypto.randomUUID error indicates an outdated browser. Ensure you’re using an up-to-date version of Google Chrome, Firefox, Edge, or Safari (released after 2021).

4. Clear Browser Cache:

   • Clear your browser’s cache and cookies to ensure no outdated or cached scripts are causing issues.
