Yeah, this is a bug. It somehow doesn't work when multiple list elements are defined in the envvar. As a workaround, you can define only one domain as host like this:

version: "3"

services:
  gotify:
    restart: always
    image: gotify/server
    ports:
      - 80:80
      - 443:443
    environment:
      - GOTIFY_DEFAULTUSER_PASS=mypass
      - GOTIFY_SERVER_SSL_ENABLED=true
      - GOTIFY_SERVER_SSL_LETSENCRYPT_ENABLED=true
      - GOTIFY_SERVER_SSL_LETSENCRYPT_ACCEPTTOS=true
      - GOTIFY_SERVER_SSL_LETSENCRYPT_HOSTS=- myhost.com
    volumes:
      - "./gotify_data:/app/data"

or you can define the config as yaml at /app/config.yml.
