❔ IISExpress keeps failing to start site

I am running this command based on Rider's run config:

C:/Program Files/IIS Express/iisexpress.exe /config:C:/Dev/App/.idea/config/applicationhost.config /site:LexisAdvance.Online.Web /apppool:Clr4IntegratedAppPool /trace:debug

C:/Program Files/IIS Express/iisexpress.exe /config:C:/Dev/App/.idea/config/applicationhost.config /site:LexisAdvance.Online.Web /apppool:Clr4IntegratedAppPool /trace:debug

I keep getting this debug output logged

I have tried using netstat as well as TCPView and can't fine port 61700 in use anywhere. I have looked all over, with ChatGPT's help and without and I can't find anything besides the usual netstat advice. I'm trying to avoid changing the port no. because the one I'm using is set up in a few projects

there could be many reasons for this possible fixes are

run as administrator
close/delete skype and teamviewer because they mess with iis
check if you have access to the port via firewall
delete temporary file

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
