Established connection with Flash-Mediaprovider disconnects immediately

MJ@alaun · Aug 18, 2017

Hello Flashphoner-team,
I got following problem:
We implementend a video-chat based on your video-chat- and conference-example. Connection and streaming with WebRTC works fine.
But in Internet Explorer 11 - using Flash - the connection disconnects immediately after the user permits Flashplayer to use its cam and mic. (Browser-console says: "11:43:04 INFO flash - Flash[a16d9c21-83f9-11e7-82f8-b9b1023cf23d]:INFO: UTC 7.18 9:43:4.650: NetConnection [NetStatusEvent type="netStatus" bubbles=false cancelable=false eventPhase=2 info=[object Object]] - level=status; description=Connection succeeded.; objectEncoding=3; data=; code=NetConnection.Connect.Success; clientid=284610969; "

11:43:04 INFO flash - Flash[a16d9c21-83f9-11e7-82f8-b9b1023cf23d]:INFO: UTC 7.18 9:43:4.774: disconnect")

The flashphoner-server-logs says: After joining the room the status is "PENDING" (2x) and after few milliseconds it becomes "FAILED" with info "Failed by error". After a few milliseconds more I got the info "Can not create session on 31350 port". I tested with tcpdump - the port receives packages from other server.

Could you please help us?
Thanks in advance
Martin

Hi, Martin
We will test it and give you feedback asap.

Max · Aug 18, 2017

We tested our video-chat in Internet Explorer 11 (Windows 7) and it's works.

Can you provide access to your server and demo?

MJ@alaun · Aug 18, 2017

Hello Max,
thanks a lot for your reply. I'm sorry, but I can't give you access because of security restrictions.
But maybe following is helpful:

I forgot to mention that our demo is running in a docker container whichs is running on a server behind our firewall. I think that the problem is a network configuration problem.
Our firewall allows connections from outside for the ports 1935 and 8443 and forwards it to the server on which the flashphoner-docker-container runs.
The docker-container listens to the ports 1935, 8443, 9091, 8888 and to the range 31000 - 32000.
We configured our flashphoner.properties like this
ip =217.7.19.61
ip_local =172.19.19.50
port_from =31000
port_to =31349
media_port_from =31350
media_port_to =31749
rtsp_port_from =31750
rtsp_port_to =32000

Do you have any experiences with Flashphoner WCS running as docker-container? Do not hesitate to ask for more information.
Martin

Hi, Martin.

Do you have any experiences with Flashphoner WCS running as docker-container?

We haven't any test WCS running as docker-container yet.

range 31000 - 32000

Are you sure that this range not busy by another process\container?

MJ@alaun · Aug 21, 2017

Good morning Max,
I looked with lsof for the ports, but the only one who uses them is our flashphoner-docker-container.

MJ@alaun · Aug 21, 2017

Maybe this helps you further?

Max · Aug 21, 2017

Hi,
we are testing WCS in docker now, will give you info asap.

Max · Aug 21, 2017

We have tested WCS at docker container and it's working without any problems both webrtc and flash streaming.
Container based on CentOS 7 started like:

Code:

docker run -p 8443:8443 -p 1935:1935 -p 31350-31749:31350-31749 -p 8888:8888 -p 9091:9091 -p 8080:8080 -i -t 4903bcbf5e4d /bin/bash

From your last logs we can see that media port 31374 is busy.
Can you send output of 'netstat -antpul' from container when this problem occurs again?

MJ@alaun · Aug 22, 2017

Thanks a lot for testing it in docker. I will test it again and check 'netstat'. Could you please give me your corresponding flashphoner.properties and server.properties?

Max · Aug 22, 2017

We have tested with config same, as at you.

MJ@alaun · Aug 22, 2017

Alright, the server-log says now PortsBusyExeception for port 31350.
This is what netstat says (called in running flashphoner-docker-container):

Is the PortsBusyException thrown because the port is busy or does it also can be thrown, when the connection to that port is not possible - for example because of firewall rules etc.?

Max · Aug 23, 2017

Hi,
this problem occurs only in Flash-video-chat case? Can you send full logs to logs@flashphoner.com ? Just archive 'logs' directory.

MJ@alaun · Aug 23, 2017

Hello Max,
I sent the logs.tar.gz to logs@flashphoner.com. Thanks a lot for checking it.

Max · Aug 23, 2017

Hi,
also, send your license to logs@flashphoner.com, please.

this problem occurs only in Flash-video-chat case?

MJ@alaun · Aug 23, 2017

I sent you the license.
Yes, the problem only occurs if Flash is involved, e.g. Internet Explorer 11 <-> Firefox. Using WebRTC, e.g. Chrome <-> FF works fine.

Max · Aug 23, 2017

How many interfaces has your docker-container? As we can from logs your WCS configured with local address 172.18.0.5, but at the same time server trying to bind to 172.19.19.50. Also, please set to false property enable_candidate_harvester and repeat your tests.

MJ@alaun · Aug 23, 2017

I got it: I didn't use the local ip of the docker-container itself but from the host. I changed it now in the flashphoner.properties and now it works in Firefox, Chrome and IE11.
I'm very sorry that I stole your time. Thank you very much for helping me

Your support is awesome!

But still a question: Do you have experience of working flashphoner in MS Edge?
When I permit the flashplayer to use my cam and mic I only see a black screen in its stage.

Max · Aug 23, 2017

I changed it now in the flashphoner.properties and now it works in every browser!

Great!

Do you have experience of working flashphoner in MS Edge?
When I permit the flashplayer to use my cam and mic I only see a black screen in its stage.

You tested Edge with WebRTC? What version of Edge did you test?

MJ@alaun · Aug 23, 2017

My Edge uses Flash immediately. If I deactivate flashplayer in its settings nothing works.
Its version is 25.10586.0.0.
HTML-version is 13.10586
(c) 2015 Microsoft

Established connection with Flash-Mediaprovider disconnects immediately
