Different between w10 and server 2019

• Issue type
This docker compose code works on a windows 10 but not on windows server 2019
Mosquitto:
image: eclipse-mosquitto
container_name: mosquitto
build:
context: ./mosquitto
dockerfile: dockerfile
ports:
- “1883:1883”
- “9001:9001”
volumes:
- .\mosquitto\config\mosquitto.conf:/mosquitto/config/mosquitto.conf
- .\mosquitto\data:/mosquitto/data
- .\mosquitto\log:/mosquitto/log

It fails on
.\mosquitto\config\mosquitto.conf:/mosquitto/config/mosquitto.conf

This works though
.\mosquitto\config:/mosquitto/config/

Is this by design or some bugg?
