Additional Information

Hello
I have a tiny pet project dockerized via docker-compose

here is the docker-compose.yml

version: "3"
services:
  api:
    build:
      context: ./api
    ports:
      - "8090:8090"
    volumes:
      - pb-data:/pb/pb_data
      - ./api/pb_data:/pb/pb_data
    environment:
      - SERVICE_FQDN_API_8090

  client:
    working_dir: /app
    build:
      context: ./app
      dockerfile: Dockerfile
    ports:
      - "3001:80"
    depends_on:
      - api
    environment:
      - VITE_SERVER_API_URL
      - SERVICE_FQDN_CLIENT_3001
      - NODE_ENV=production

This is the second resource in my project with the same stack; the only difference is the ports. The OG resource works fine, but this one has a problem with the client container; it shows 502 via domain but is accessible via a direct ip+port combination.

What I've trie already.

• recreate a resource from scratch
• change 3001 port to any random one
• rename client image and SERVICE_FQDN_ variable
• try to use node, bun, and nginx for the static server
• add another subdomain both for API and the client, for API both work find and non of them for the client
  UPD:
• I've tried to add a new subdomain from a different domain names provider

I'll be glad to provide some debug information
