Site Logo and Icons Break due to subfolder config

[Stephen]

Out of curiosity why are you going through the pain of a subfolder install?

@neil

It is critical you have a deep understanding of

• NGINX setup in the Discourse Docker container
• Secure original IP forwarding using custom headers in the proxy chain
• Rate limiting in front proxy server

If this all sounds odd and strange to you we strongly recommend you avoid this setup.

This seems to be very relevant to your situation. A lack of understanding of the concepts here is going to keep coming back and biting you.
