Enterprise v2 issue with jitter on azure

Question

Hi 
So I created a new VM on Azure using the enterprice v2. default setup no changes to the server other then opening the ports, assigning an certificate and setting it cluster mode.
I'm using it this as origin server, it's in the same region and network as my version 1.9.* origin server. and server size is same also.

streamed to the new server at same settings i used before on the version 1.9.* server  (1080p 24fps 3000kbps ABR is disabled. h264, no mp4 recording webrtc rtmp.  )
and the result was 1 i could not playback the vid on the webportal , but the stream did playback (wss) on my site but with major jittering (framedrops) going on but the upstream quality "good", speed >1 around 1.1-1.2

i the switched to my server with 1.9.* and then then i could now see the playback in the webportal and the stream on my site was smooth again. 

so using same stream quality, same server configuration, same ant media config. but version 2.0 major jittering, while version 1.9 no jitter.

i then reduced the stream quality to 720p 1000kbp, but still same jittering on version 2.0

I then enabled ABR, and defined a 1080p kbps 3000 ftp 24 stream, and restarted the stream to same setting. and now version 2.0 was smooth playback

so there is something going on here with the azure enterprise 2.0 setup. 
could it perhaps it has something to do with the "RTMP bufffering" which i see then release notes where added.  how can we control that?
what's going on here does the stream become smooth only with enabling ABR ?


Kind regards
Jan

I had the same problem on AWS. What fixed it for me was to remove ?rtmpForward=true  from the client's URL that was the request to the server
