@evalalos do you have Nginx or another reverse proxy behind Selenoid UI?

Hello @vania-pooh it seems I have very similar problem with SSE. I use this docker-compose.yml:

version: '3'
services:
  selenoid:
    image: "aerokube/selenoid:latest-release"
    network_mode: bridge
    ports:
      - "4444:4444"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "~/Documents/config/:/etc/selenoid/:ro"
    command: -limit 20 --timeout 3m
  selenoid-ui:
    image: "aerokube/selenoid-ui:latest-release"
    network_mode: bridge
    links:
      - selenoid
    ports:
      - "8042:8080"
    command: ["--selenoid-uri", "http://selenoid:4444"]

After their start I see the errors in the selenoid-ui Endpoint http://selenoid:4444/status response with an error: {"errors":[{"msg":"can't get status"}],"version":"1.10.4[2021-10-10_08:53:47AM]"}. I'm using the latest Docker for Mac v4.1.1. Could you please give me any advise on what should I check to figure out what is the problem?

[dvdvdmt]

I figured out that the problem disappears on the old Docker Version 4.0.0 (4.0.0.12). But only in case you go to the Preferences > Experimental Features and disable "Use Docker Compose V2 release candidate". The fresh docker of v4.1.x doesn't have such setting.

[dvdvdmt]

There is also a command that switches Docker Compose V2 back to Python's docker-compose:

docker-compose disable-v2

Here are the details.
