Minio and proxy with WSL2

I have followed the tutorial here Deploy MinIO Object Storage to · Fly Docs, have successfully deployed and want now to proxy

fly proxy 9001 
Proxying local port 9001 to remote [test-minio.internal]:9001

However when hitting http://localhost:9001/ in my webbrowser nothing happens, infinite loading.
I suspect it might be linked with WSL2.
I have already used proxy with Postgres it has worked well. Not sure why it isn’t working here.

This does seem like a WSL issue. Are you able to connect to http://localhost:9001 from inside WSL (with curl or similar)?

Thanks for your help, unfortunately even with curl http://localhost:9001 no response (it is stuck not even error)
I can see that the proxy commands kind of work with

fuser 9001/tcp   
9001/tcp:            14526

Before there was no process using 9001 port.

On monitoring I have these logs if that helps:
