VSCode Devcontainers Port forwarding doesn't work properly on remote server

Question

Overview

I am trying to run VSCode Devcontainer on my remote server for development with PHP and Nginx. It works perfect if I connect to the server via VSCode SSH and run docker-compose.yml manually on port 8081. The issue is that it doesn't work when I open project in VSCode Devcontainer (it has white screen with infinite loads and logs are clear).

Have you ever come across this?

.devcontainer/Dockerfile

FROM mcr.microsoft.com/devcontainers/base:ubuntu-22.04

ARG NGINX_VERSION=1.25

.devcontainer/php/Dockerfile

ARG PHP_VERSION=8.3-fpm
FROM php:${PHP_VERSION}

What did I try

1. I tried to run docker-compose.yml via VSCode SSH Remote manually by typing docker-compose up -d and it works perfect. It forwards host localhost:8081 to localhost:8081 and I can see content of index.php file.

• Content: localhost:8081
• VSCode: PORTS tab
• Docker: compose -up d && docker ps

2. I tried to set up Docker host in VSCode by adding code below following Develop Remote Host documentation

"docker.environment": {
    "DOCKER_HOST": "ssh://your-remote-user@your-remote-machine-fqdn-or-ip-here"
}

3. I tried to change port for all services
4. I tried to set up launch.json file to run PHP in workspace manually

Guess

In general I understand why it happens. I think it forwards ports from Docker Remote Server to Remote Server instead of forwarding from Docker Remote Server to Local Environment, but how to tackle it I don't know.

Expectations

I want to run VSCode Devcontainer on remote server instead of VSCode SSH Remote. In result, I should be able to develop in VSCode Devcontainer on the my own remote server. In addition, PHP and Nginx should work without any issues.
