Azure function run attempt failing

[wordBoy]

I am trying to run a new HTTP Trigger Azure function locally, but it is failing with the following log. I did try to add my proxy information to local.settings.json but that had no effect - however that did result in the "Skipping" notes below.

Azure Functions Core Tools Core Tools Version: 4.0.4629 Commit hash: N/A (64-bit) Function Runtime Version: 4.6.1.18388

Are there any updates regarding this? I encounter the same error on an WSL2 System after freshly installing for version:

Azure Functions Core Tools
Core Tools Version:       4.0.5455 Commit hash: N/A  (64-bit)
Function Runtime Version: 4.27.5.21554

Can I provide any addtional input, that helps resolving this issue?

Following since I'm seeing it sometimes locally as well.

This is just a wild guess, but since you mentioned only fiddling with proxy settings from the app settings and prints seem to state they are skipped, are you missing localhost from NO_PROXY? So do you have something in NO_PROXY env, but not this localhost stuff?

I do this in powershell to be able to do dotnet run:

$env:NO_PROXY="$env:NO_PROXY,localhost,127.0.0.1"
