Hello,

I’ve try to build a local wowza streaming engine and I found something different. I want to move whole wowza instance from AWS to my local datacenter.

I found something different between AWS vs Local Installation, my previous thread about [Video did not appears on Apple Device using Safari](http://community.wowza.com/t/-/45034) make me more curious about the configuration, but I was though is not the configuration, but something missing (hardware?).

My question is, did amazon aws has a GPU for instance [Amazon Wowza](https://aws.amazon.com/marketplace/pp/B00IPTQDI6/ref=mkt_wir_wowza) m2.xlarge ?

Hi,

It may be a firewall configuration, ie. ports were open properly on the AWS instance, but not on the local data-center instance.

Consider what port you are trying to play over, wither the standard Wowza streaming port 1935 or the default http port 80.

> Nope.

Then why the result could be different between the local setup with the aws setup?

The source are same, when I change to aws, the apple HLS can play normally from their browser (safari).

But if i set the wowza stream engine to local, the HLS can’t play anymore.

Any method to debug/analyze it?
