[Python] Debugpy Connection Refused Debug in VsCode

Good morning. Since yesterday I can't seem to connect to my debugger using debugpy. I'm getting a ECONNREFUSED error, I haven't really changed anything and can't seem to connect to my debugger. Debugpy starts listening to the port, but vscode can't connect to it.

This is my debugpy script:

import os
import debugpy
os.environ['PYDEVD_DISABLE_FILE_VALIDATION'] = '1'
if os.environ.get('DEBUG','false').lower().strip() == 'true':
debugpy.listen(("localhost", 5678))
print("Waiting for debugger attach on port 5678...")
debugpy.wait_for_client()
print("Debugger attached!")


This is my Vscode launch.json

{
"version": "0.2.0",
"configurations": [
{
"name": "Serverless Debug",
"type": "python",
"request": "attach",
"port": 5678,
"host": "localhost",
"console": "integratedTerminal",
"pathMappings": [
{
"localRoot": "${workspaceFolder}",
"remoteRoot": "."
}
]
// ,
// "pythonArgs": [
// "-Xfrozen_modules=off"
// ]
}
]
}


also tried this:

{
"version": "0.2.0",
"configurations": [
{
"name": "Serverless Debug",
"type": "debugpy",
"request": "attach",
"connect": {
"host": "localhost",
"port": 5678
},
"pathMappings": [
{
"localRoot": "${workspaceFolder}",
"remoteRoot": "."
}
]
}
]
}


Has anyone else experienced this?
