I could not access newly created web application in SharePoint Central Administration.

"I could not access newly created web application in SharePoint Central Administration."

It was the problem that bothered me today.

After strenuous efforts, I resolved it.

I installed SharePoint Server 2019 on Windows Server 2019 in VMware Workstation 15 Pro.
Then I created a new web application using default settings.

Web application jsguru.group.com:29457 was created. See screenshot below.

So far so good.
But when I tried to access the web application in VM machine I had worked on, I could not.

Let me show you how I resolved it.

Step 1. Add the web application name (here jsguru.group.com) to the string value of BackConnectionHostNames under
windows registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0.
If there is no entry BackConnectionHostNames, you have to create it as multi-string value.

Alternatively, create DWORD-value entry DisableLoopbackCheck with value 1 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa.(This is not recommended)

Step 2. Add the IP address and host name of the web application to the bottom of the hosts file. The hosts file path is C:\Windows\System32\drivers\etc

Thus I could get access to the web application.

I hope this helps someone who is trying to do the same thing like me.
