as a workaround you could add to gui section in docker-compose.yml
(in the top level directory) environment variable GATEWAY_IP=yourdomain
so it looks something like this:
mender-gui:
image: mendersoftware/gui:2.1.0b1
extends:
file: common.yml
service: mender-base
networks:
- mender
environment:
- INTEGRATION_VERSION
- MENDER_ARTIFACT_VERSION
- MENDER_VERSION
- MENDER_DEB_PACKAGE_VERSION
- GATEWAY_IP=my.mender.server
