Hey,
I have the same problem. I use docker and nginx

docker-compose file

version: '3.1'

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "127.0.0.1:5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=urs
      - N8N_BASIC_AUTH_PASSWORD=pas277
      - N8N_HOST=n8n.cybershu.eu
      - N8N_PORT=5678
      - N8N_PROTOCOL=http
      - WEBHOOK_URL=https://n8n.cybershu.eu/
      - VUE_APP_URL_BASE_API=https://n8n.cybershu.eu/
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./n8n:/root/.n8n

nginx configuration file:

server {
    server_name n8n.cybershu.eu;

    location / {
        proxy_pass http://localhost:5678;
        proxy_buffering off;

        chunked_transfer_encoding off;
