What happens ?

I have been debugging Python Azure Functions for more than 2 years. Yesterday (1.Oct.2025) I noticed that debugger does not work anymore.

I press F5, the function starts succesfully, but then the debugger complains with: 'connect ECONNREFUSED 127.0.0.1:9091'

My lauch.json looks like

```json
{
"version": "2.0.0",
"configurations": [
{
"name": "Attach to Python Functions",
"type": "debugpy",
"request": "attach",
"connect": {
"host": "localhost",
"port": 9091
},
"preLaunchTask": "func: host start"
}
]
}
```
