Why do I get errors when MediaLive tries to write data to MediaStore ?

Question

I'm getting some errors when I try to do a live stream using MediaLive. In MediaLive, I have a RTMP(push) input and MediaStore configured as destination.  
  
For MediaStore I have configured container policy like here:  
https://docs.aws.amazon.com/mediastore/latest/ug/policies-examples-default.html  
I enabled Cloudwatch logs for the MediaLive channel and these kind of PUT failed errors show whenever I start streaming.

```
Setting alert [6006] [1-2] [6006-1-2] [OutputDataS3: PUT failed [mediastore://xyz.data.mediastore.us-west-2.amazonaws.com/mystreams/stream_720p30_00005.ts] size [549148]. Response=[403] Message[] Headers[x-amzn-RequestId: EHYZJ3SDA4KJBHRSPELTDV2KW5FUAWVDJYWBC2VPYR7WHWOBDNFGIH3HEAJUJ]
```

Also in the channel's alert section, I see erros like this:

```
Failed to Create Output File or Socket
MPEGTS muxer for mediaID [1] unable to open output or stream [mediastore://xyz.data.mediastore.us-west-2.amazonaws.com/mystreams/stream_720p30.000007.m3u8].
```

For debugging purposes I've gave full access to the IAM role that is associated with the channel.  
  
Any idea on what I'm missing ?

When writing to AWS Elemental MediaStore you should use "mediastoressl://" instead of "mediastore://".   
  
See https://docs.aws.amazon.com/medialive/latest/ug/hls-protocol-fields.html & https://docs.aws.amazon.com/medialive/latest/ug/hls-destination-complete-fields-step.html as reference.  
  
Additionally in the HLS Output Group settings - HLS Settings - CDN Settings should be set to HLS MediaStore.

Answer

_mediastoressl_ did the trick. I'll also change the _hls webdav_ to _hls media store_. Live stream also works with _webdav_, but I need to read more about the difference between them.   
  
Thanks @fxeataws !
