Nifi web page does not start Windows 2008 Server R2

Carolyn — Tue, 10 Apr 2018 21:57:24 GMT

Nifi installed on Windows Server 2008 R2 using the Windows msi without any errors. The service starts up but when I attempt to open nifi in the Web browser using http://localhost:8080/nifi, I get the Nifi water drop but the canvas never appears.

The error appears in the nifi user log. Do I need to enable HTTPS?

@cduby

Look for this line in your nifi-app.log file

The UI is available at the following URLs:

What URLs do you see?

@cduby

Try one of those URLs instead of localhost.

@Wynner I see the same problem with both of those URLs.

I tried on Windows Server 2012 and had the same issue.

I am creating my windows instance in AWS using the Windows Server with SQL Server.

I resolved the issue by using a different browser. The version of Internet Explorer I was using did not work. I resolved the issue by allowing the 8080 port through the windows firewall and then connecting remotely using Chrome.
