pydPiper cannot connect to Volumio 3.198 HTTP error [Errno -2] Name or service not known

[DaPiMan]

I've been trying to troubleshoot this issue and not having much luck.

I have a hd44780_i2c 16x2 display connected to my RPi4 running Volumio 3.198 and installed pydPiper from cloning the GIT to my PC and installing docker/volumio .sh scripts.

Docker is running and pydPiper service is running but I see the following in the log and nothing on the display:

2022-03-24 22:21:39,823:DEBUG:Starting new HTTP connection (906): audiostreamer.local 2022-03-24 22:21:39,841:WARNING:audiostreamer.local:3000/socket.io [engine.io waiting for connection] HTTPConnectionPool(host='audiostreamer.local', port=3000): Max retries exceeded with url: /socket.io/?EIO=3&transport=polling&t=1648160499821-0 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x1625510>: Failed to establish a new connection: [Errno -2] Name or service not known',))

Accessing audiostreamer.local/socket.io/?EIO=3&transport=polling&t=1648160499821-0 via chrome on my windows machine results in a file called "download" downloading with the following text:

ÿ0{"sid":"2nomW53Hw952M9qCAAAD","upgrades":["websocket"],"pingInterval":25000,"pingTimeout":60000}

I get the feeling that Docker is being blocked on port 3000; even thought pydPiper is started with --network=host which should technically open/let it see Volumio on port 3000.

Does anyone have any idea what the issue might be?

I was able to get a bash shell into the docker container and realised the docker couldn't resolve .local after removing .local the service successfully started but no dice getting anything on the 16x2 display as yet.

Getting the following now:
