Hi, Good Day,

I just want to know if what can be the problem when some devices, specially mobile phones cannot play the streams?

I tried to remote inspect using chrome (a mobile phone is connected), then I noticed
that the webrtc adaptor callback is always getting 'play_finished'.

This is with or without VPN.

Let me know if I can provide something to help with the checking.

Also, We use enterprise edition in aws ec2, so it is paid,
And we already submitted an email, but no one replies.

Regards,

ejgp...@gmail.com

I'm not sure if I capture all on server log for that particular device because our log is polluted by dts:

Hello Ejgperion,
Thank you for the logs.
Can you please refer to my previous mail. It would be great if you can provide the dashboard credentials, you can change the same later.
I have tested the stream by playing in Mobile browser and it worked fine for me. So if you can provide the related info or a reproduce scenario, it will help us to understand the same.

Hello,

I'm not sure If I received that mail that you mentioned.

We are using the javascript sdk. but even the test page, player.html cannot be played on some devices.

"I have tested the stream by playing in Mobile browser and it worked fine for me. So if you can provide the related info or a reproduce scenario, it will help us to understand the same."
- Yes, some device works, some do not, it's really weird.

We can arrange a remote session if you need (anydesk or teamviewer), we have a device that the video is not working. so we can check from there.

Regards,
Emman

Hello Emman,
​It appears that there is some issue with network, either with symmetric NAT or Firewall.
Can you please confirm if there is Firewall which might block traffic and whether UDP port range 5000-65000 is open.

Hello,

Yes, we can confirm that there is no firewall, because on that same network where we test, other phones and laptops can play the stream, but this galaxy a32 cannot.

And yes, udp ports is open:

Also, would you know what is causing these to appear on the logs?

Hello Emman,
Thank you for that. If the issue is only with Galaxy A32 we can check for it and see for some workarounds.

Scenarios:
- same network, laptops is working, but phones is not.
- wifi connection on phone will not work but lte will work
​
Does it mean that you are able to play the stream on mobile when using mobile network (LTE) but now when using wifi!

Also, would you know what is causing these to appear on the logs?

Hello,

Yes, on our test environment, this said device can play the video on lte network, but not on wifi.
but at the same time, a laptop can play the stream on that same wifi network.

It's really weird, but it's stressing us out because more and more client now complains that they cannot see the video.
So we really need your help.

Internet connection and/or speed is not a problem, clients were on Korea, where internet is very stable and fast.

If you can provide the Dashboard credentials we can look into both the cases of Galaxy A32 as well as Dash.
Also, has there been any other cases where you haven't been able to play the stream apart from Galaxy A32 on Wifi?
