Failed to set session cookie. Maybe you are         


        

Answer 1

I had this issue because I am hosting phpmyadmin behind an nginx reverse proxy, using Docker Compose. In my docker-compose.yml file I had:

db-admin:
    # https://hub.docker.com/r/phpmyadmin/phpmyadmin/
    image: phpmyadmin/phpmyadmin:latest
    restart: always
    environment:
      - PMA_ARBITRARY=1
      - PMA_HOST=http://db
      - PMA_PORT=3306
      - PMA_ABSOLUTE_URI=http://localhost/db-admin/  # necessary because the db-admin is hosted behind a reverse proxy.
    ports:
      - 8084:80
    depends_on:
      - db
    networks:
      - shared-network

Due to the reverse-proxy and the PMA_ABSOLUTE_URI, I can only use this application on http://localhost/db-admin, not on http://localhost:8084.
