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?

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.

Look for this line in your nifi-app.log file
The UI is available at the following URLs:
What URLs do you see?

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.
