Hi All,

When i am going to create new web application or extending the existing web application using Central Administration.

It throw error:

ULS Log Error shows:



Unexpected System.UriFormatException: Invalid URI: The hostname could not be parsed.    at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)     at Microsoft.SharePoint.Administration.SPVirtualServer.InitializeIisComponents(SPIisWebSite iisInstance)     at Microsoft.SharePoint.Administration.SPVirtualServerCollection.Undirty()     at Microsoft.SharePoint.Administration.SPVirtualServerCollection..ctor()     at Microsoft.SharePoint.WebControls.IisWebSiteSection.PopulateIisWebSiteDropDownList()     at Microsoft.SharePoint.WebControls.IisWebSiteSection.OnLoad(EventArgs e)     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Control.LoadRe... f1a5899c-4b18-50d4-9421-ecd319658fa8

Hi Manoj,

This issue may be about permissions of the user that you used. Please use a farm account to log in CA, and test again, compare the result.

Hi Manoj,

According to your description, my understanding is that you got an error when you created or extended a web application in SharePoint 2013 Central Administration.

Please try to create or extend a web application using PowerShell command, compare the result.

Creating a new web application using PowerShell command:

$ap = New-SPAuthenticationProvider

New-SPWebApplication -Name <Name> -ApplicationPool <ApplicationPool> -ApplicationPoolAccount <ApplicationPoolAccount> -URL <URL> -Port <Port> -AuthenticationProvider $ap

Extending a existing web application:

Get-SPWebApplication -Identity http://sitename | New-SPWebApplicationExtension -Name <Name> -HostHeader <HostHeader> -Zone <Zone> -URL <URL> -Port <Port> -AuthenticationProvider $ap

More information, please refer to the link:

I hope this helps.

Thanks,

Thanks Wendy, your understanding is correct !!

I tried that power shell script, Its working

Add-PSSnapin "Microsoft.SharePoint.PowerShell" 
$ap = New-SPAuthenticationProvider
New-SPWebApplication -Name "Contoso Internet Site" -Port 2002 -URL "http://a2ms06873" -ApplicationPool "NetworkService" -ApplicationPoolAccount (Get-SPManagedAccount "DomainName\Administrator") -AuthenticationProvider $ap 

what can be the reason, i am not able to create or extent the web application using Central Administrator.

Thanks

I ran into the same error.   It was because I had an asterisk instead of a full host name in the bindings in IIS for  another web application.  Once I edited the bindings and added the hostname, I was able to create a web application using Central Admin.

+1 for the asteric in the bindings of the website.  mistakenly did that when I added the cert and edited the bindings when we went SSL.

Exactly this is what happened to me when setting ssl in sp2019, and replacing that asterisk with address solved the problem.
