Visual Studio localhost IIS Server Not Found - asp.net

Question

I'm trying to run an ASP.NET webforms website that I downloaded from an FTP server, but I'm running into problems when I try to build and run the project.
When I build and run the website, it opens my browser window, but adds "www." before the localhost address and I get a server not found error. I'm able to successfully build and run other websites, so I think I must have something wrong in the web.config or website properties. Here's a screenshot of my browser window:
Visual Studio Version: 15.7.2
IS Express: 10.0.1743
I tried changing the IIS port being used in the application.config file to see if that helped, but it gets replaced by a new site tag after I edit the original one. For example if my original port is 51060 and I change it to 51065 like this:
<sites>
<site name="WebSite1" id="1" serverAutoStart="true">
<application path="/">
<virtualDirectory path="/" physicalPath="%IIS_SITES_HOME%\WebSite1" />
</application>
<bindings>
<binding protocol="http" bindingInformation=":8080:localhost" />
</bindings>
</site>
<site name="mywebsite" id="2">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\me\Documents\mywebsite" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:51065:localhost" />
</bindings>
</site>
<siteDefaults>
<logFile logFormat="W3C" directory="%IIS_USER_HOME%\Logs" />
<traceFailedRequestsLogging directory="%IIS_USER_HOME%\TraceLogFiles" enabled="true" maxLogFileSizeKB="1024" />
</siteDefaults>
<applicationDefaults applicationPool="Clr4IntegratedAppPool" />
<virtualDirectoryDefaults allowSubDirConfig="true" />
</sites>
The application.config file changes to:
<sites>
<site name="WebSite1" id="1" serverAutoStart="true">
<application path="/">
<virtualDirectory path="/" physicalPath="%IIS_SITES_HOME%\WebSite1" />
</application>
<bindings>
<binding protocol="http" bindingInformation=":8080:localhost" />
</bindings>
</site>
<site name="mywebsite" id="2">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\me\Documents\mywebsite" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:51065:localhost" />
</bindings>
</site>
<site name="mywebsite(1)" id="3">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\me\Documents\mywebsite" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:51060:localhost" />
</bindings>
</site>
<siteDefaults>
<logFile logFormat="W3C" directory="%IIS_USER_HOME%\Logs" />
<traceFailedRequestsLogging directory="%IIS_USER_HOME%\TraceLogFiles" enabled="true" maxLogFileSizeKB="1024" />
</siteDefaults>
<applicationDefaults applicationPool="Clr4IntegratedAppPool" />
<virtualDirectoryDefaults allowSubDirConfig="true" />
</sites>
Thanks for any help.

Right click on your web forms application project and then properties, navigate to the Web section, then look at the Servers section, and look at the Project Url that is being used, you can also mark the option Override application root URL if needed.
I hope it helps.
