asp.net mvc web app is not running on defined port in IIS express 10.0

Question

I am working on asp.net mvc web application project in visual studio 2015 with .NET framework 4.5. it was configured to run over ssl port 44302. i had to format my OS. After re-installing everything. it changed to run over other port. when i try to change port manually now it is not working. i re-installed iis express. deleted ssl and using netsh.

still can't able to make it work on port 44302. when i set this to port 44302. iis express does not start it. i am worried if i need to re-install OS or can i solve this. please have a look in picture>

Answer 1

未选中“覆盖应用程序URL”复选框，因此不会覆盖该URL。

Answer 2

visual studio 2017 localhost didn't send any data under SSL. I found that the proxy setting for localhost had been hi-jacked by a video downloader program. Went to network settings > proxy and turned it off. Suddenly working!!
