Im trying to run Apache NiFi on my laptop. I can start the run-nifi.bat But when I try to access http://localhost:8443/.  "This page isn’t working localhost didn’t send any data. ERR_EMPTY_RESPONSE"

On the same laptop, I'm accessing different NiFi instances running on AWS. With different ports (Production).

System: Windows10

Please help to connect

I wonder what java version you have on your Windows machine?

NiFi supports java 8 and 11

First confirm if the NiFi JVM is running

search your logs for the word "UI is available"

If it is then I would look at your systems firewall windows defender?

If you do not see that log entry I would focus on why NiFi JVM is not coming up
