Splunk Stream not working

[windsurfer30]

This is driving me nuts, I'm trying to setup splunk stream for netflow.

I've uploaded the app and at the end of the upload it gives me an error: Error connecting to /servicse/apps/local: timed out

Nonetheless one of the messages prompts me to restart Splunk so I do. And I see the Splunk Stream app but when I go to it, it comes up blank. The logs say
2019-11-06 09:25:36 ERROR 140167464486656 stream.CaptureServer - Unable to ping server (9c5d65be-af86-4b47-b0e3-cb31198ab475): /en-us/custom/splunk_app_stream/ping/ status=404

Why would I be getting 404 errors on a default install?
the splunk system local web.conf has the httpport set 8000

if I wget the URL on localhost:8000 I get
Connecting to localhost (localhost)|127.0.0.1|:8000... connected.
HTTP request sent, awaiting response... 404 Not Found
2019-11-06 09:31:39 ERROR 404: Not Found.

please help?

Nevermind. I was trying to run it on Splunk 8.0 switched to splunk 7.3.2 and working now

Forgot to mention that I also did run the ./set_permissions.sh script as indicated in the instructions

And in the GUI if I click and try and open splunk_app_stream it goes to
... en-US/app/splunk_app_stream/info_overview

but the whole page is blank
