Server never starts when using Docker + Volumes

Trying to get a persistent volume attached so that I can use this image for hosting. When attaching to a local volume (and also a volume in Azure), it hangs on the "Downloading Bedrock server version 1.17.10.04 ..." step and never progresses.

Output from console (Azure Container Instance):
```shell
time="2021-08-04T19:05:30Z" level=debug msg="Using /data to match uid and gid"
time="2021-08-04T19:05:30Z" level=debug msg="Resolved UID=0 from match path"
time="2021-08-04T19:05:30Z" level=debug msg="Resolved GID=0 from match path"
Looking up latest version...
time="2021-08-04T19:05:30Z" level=debug msg="stdin is detached, so forwarding is disabled"
Downloading Bedrock server version 1.17.10.04 ...
```

Here's my docker-compose.yaml file:
```yaml
version: "3.4"

services:
bedrock-server:
image: itzg/minecraft-bedrock-server
volumes:
- mcdata:/data
environment:
EULA: "TRUE"
GAMEMODE: survival
DIFFICULTY: normal
domainname: "bedrock"
ports:
- "80:80"
- "19132:19132/udp"
stdin_open: true
tty: true
sysctls:
net.ipv4.ip_local_port_range: 39132 39133
deploy:
resources:
reservations:
cpus: "2"
memory: 4G

volumes:
mcdata:
driver: azure_file
driver_opts:
share_name: mcdata
storage_account_name: azurestorageaccount
```

When I remove the custom volume from this compose file, it all works as expected (in Azure and on local Docker Desktop). Thanks for the help!

Start with the supplied docker-compose.yaml and reproduce the hang using the mcdata volume configuration, comparing it with the no-volume case. Trace the container's /data initialization and Bedrock download entry point, using the console output to locate where progress stops. Done means the server starts and completes its download with a persistent local or Azure volume.
