Hi,
I dont suppose you managed to get an answer to this? I hope you don't mind me posting here - rather than a new similar post - hopefully two of us asking a related question is more likely to get an answer? Or maybe some of the stuff I tried below might help you?
If you rather I create my own thread please let me know..
I have docker running on my Mac M1 which is running a server container accepting WebSocket connections on port 15000. I can connect to it fine from within MacOS - but when I try from the parallels Windows VM - I am not able to connect.
I searched this forum and noted that the Mac host machine is allocated an IP of 10.211.55.2, so I tried connecting to 10.211.55.2:15000 - but nothing.
I also tried adding 10.211.55.2 host to the windows\system32\drivers\etc\hosts file - and then tried using host:15000 - but still no joy..
