VS2015 - Unable to connect to the configured development Web server

  • Article

Question

Friday, February 8, 2019 11:43 PM

Initially, I was trying to test my website using an iPad and googled for ways to do that. After getting results from Stack Overflow and also some of the other websites, I tried different things to achieve that but did not have much luck. But, in trying those different things I broke how my website was running using a browser. Now, whenever I try to run it using a browser,  I get this error:

"Unable to connect to the configured development Web server."

The type of the project that I have is "Web Site". 

I have tried the following:

1. Deleted C:\Users\Me]\Documents\IISExpress folder

2. Deleted applicationhost.config under .vs directory in the solution directory

3. Deleted the .vs directory

4. Ran

netsh http add urlacl url=http://{ip_addr}:{port}/ user=everyone

5. Restarted Visual Studio several times

6. Restarted machine several times

7. Uninstalled Visual Studio 2015 (Professional edition) and IISExpress 10.

8. Reinstalled Visual Studio (which reinstalled IISExpress 10)

Any help is appreciated.

The problem has been fixed.

Yes, I tried other browsers and rebooted the machine several times with no luck.

The fix was to add 0.0.0.0 to the IP listen list per https://stackoverflow.com/questions/32190881/how-to-solve-err-connection-refused-when-trying-to-connect-to-localhost-running/45199591#45199591

netsh http add iplisten ipaddress=0.0.0.0

in the command prompt running as administrator.

Thanks for all your help.

Hi Debarupa,

Welcome to the MSDN forum.

>> Now, whenever I try to run it using a browser,  I get this error:

Do you meet this issue for other website applications? Please try to create a new website application and confirm this issue occurs or not.

According to the error message, please have a try with the following:

  1. Run VS as administrator
  2. Right click the project name, Properties-Server and change the project URL to other port
  3. Delete the temporary ASP.NET Files located: C:\WINDOWS\Microsoft.NET\Framework\v4.0. 30319\Temporary ASP.NET Files\root

Best regards,

Sara

Yes, I created a new website and tried to run it using the browser and the same error popped up.

>>According to the error message, please have a try with the following:

  1. Run VS as administrator
  2. Right click the project name, Properties-Server and change the project URL to other port
  3. Delete the temporary ASP.NET Files located: C:\WINDOWS\Microsoft.NET\Framework\v4.0. 30319\Temporary ASP.NET Files\root

Here's what I did:

1. Ran VS as administrator

2. Right clicked the project name, Properies, but there is no "Server" and the project URL port cannot be changed as they are disabled in both "URL" and "Opened URL" settings. Please note that mine is a web site not a web application.

3. deleted the temporary ASP.NET Files as mentioned.

Still see the same error.

Meanwhile, we can reboot the computer and try it again.
