Experiencing a lot of disconnections after 30-63 seconds

Is there a way to instruct the server or the client to try and keep the connection rather then throw
STREAM_STATUS.FAILED
upon small disconnections ?

most issues are on mobile (iphone and android) but also on some desktops.

Here is my server setup:


port_from =30000
port_to =31000

I have tested iphone 7 with 12.2 - got disconnected after a minute- both on 4g and on wireless.
This wasn't so bad before.
continuing my previous question - how can I debug this ?

Good day.
Unfortunately, we did not receive your logs by email. You can place logs on any resource and send us a URL link to download.

To solve problems with a stream ("Experiencing a lot of disconnections after 30-63 seconds"), use WebRTC stream publishing over TCP.
WebRTC over TCP usage is enabled with the following parameter in flashphoner.properties file:
Code: 
ice_tcp_transport=true
Restart WCS:
Code: 
systemctl restart webcallserver
For these settings, you need WCS version 5.2 and above.

now one side of the stream is alive but the other side (we use 2 streams )
but I see now that the video has lags that it didn't used to have before.

This works for 12.2 but not for 12.3.1 - they keep disconnecting after short period.

Good day.
We checked your server log. Stream publishing stops by RTP activity timeout, it means client stops sending media data. The possible reason may be device orientation changing (turning from portrait to landscape adn vice versa), in this case iOS Safari stop sending video.
The latest WCS builds support WebRTC picture rotation using orientation extension. Here is feature detailed description and usage example for stream publishing. Note that this feature is supported since build 5.2.136 so it would be better to update WCS to latest buils from this page.

This is not rotation issue - the phone is sitting on a desk.
We're on 5.2.146 on the server. and latest sdk available (may 27th)
I will update the server to 175.

Please check also if streaming from iOS is stopped using example application (Two way Streaming or Media Devices).
