Failed to log in invalid session try restarting your game and the launcher

[barseghyanartur]

I have the Minecraft server running using this docker-compose.yml:

version: "3"

services:
  mc:
    image: itzg/minecraft-server
    ports:
      - 25565:25565
    environment:
      EULA: "TRUE"
      DEBUG: "TRUE"
    tty: true
    stdin_open: true
    restart: unless-stopped

Minecraft server version is 1.18.1.

I'm using the TLauncher (for Linux) version 1.18.1.

I can add the server in the list of servers. It reports OK. However, I can't connect to the server due to the following error:

Failed to connect to the server.
Failed to log in: Invalid session (Try restarting your game and the launcher).

I do restart the game and the launcher, but the error persists. Any tips? Thanks in advance!

You have to pass ONLINE_MODE: "FALSE" in your environment variables, put it below DEBUG for example.
