@ijokarumawak I can't seem to get this to work properly. I configured nifi
to allow http site-to-site only, not secure. I then connected a
GenerateFlowFile processor to a Remote Process Group that points back to
http://localhost:8080/nifi with the only port that I have. I ensured that the
port was running and transferring data to an UpdateAttribute processor that
ends the flow. When I start sending data to the RPG, though, no data is sent,
and the logs show the following every 60 seconds:
```
