Attempts to bind on port 8080 despite specifying port on both urls

[cryolithic]

Description

When attempting to run from a powershell prompt, I am unable to start the application as it fails to bind on port 8080. There is an application running on that port that cannot be stopped or moved to another port.

Configuration

Server 2019
x64
I have not tried this on another system yet
from powershell command line:

dotnet monitor collect --urls http://hostname:52323 --metricUrls http://hostname:52325 --no-auth

Regression?

I am unsure if this previously worked. First attempt to use the tool

Welcome to dotnet-monitor!

Thanks for creating your first issue; let us know what you think of dotnet-monitor by filling out our survey.

Can you check if the environment that you are trying to run .NET Monitor in has ASPNETCORE_URLS set to http://+:8080? By default, .NET Monitor will bind to https://localhost:52323 and http://localhost:52325 unless some other environmental setting overrides those.

[jander-msft]

I think you have some other configuration element that tells .NET Monitor to use port 8080 (and something is already running on that port). You can also use dotnet monitor config show --show-sources to write out the effective configuration that .NET Monitor is observing; it should have a "urls" property that'll tell you which configuration element is causing it to bind to port 8080.

Please feel free to open again if you are still having this issue.
