Hi
Now that you have upgraded to Wowza 3.1.1 you will need to tune the server again.
This server is running with 1 processor, follow the tuning guide here,
https://www.wowza.com/docs/how-to-do-performance-tuning
The vod application should work, check how to play using this tutorial,
https://www.wowza.com/docs/how-to-set-up-video-on-demand-streaming
I think that the live application isn’t working because the /applications/live directory is missing. Follow this tutorial to make a live application,
