Error 1009: Could not fetch STUN/TURN when connect from difference domain

[bin tom]

Hi!

i develop a web page on iis ( https://domain1.com) , to connect to BBB (https://domain2.com) using example Javascript API (demo11.jsp) then everything work with flash for audio. But can not enbale webrtc for audio,bbb display: " Detected the following WebRTC issue: Error 1009: Could not fetch STUN/TURN server information. Do you want to try Flash instead?) "

On Browser (chrome, firefox) debug mode it display:" Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://domain2.com/bigbluebutton/api/stuns?sessionToken=a3geip6ebawtbmgh. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing) "

i already enable Cross-Origin Request on domain1.com

So how can i solve it.

Please help!

Thanks and regards

Hi,

Serving up the BigBlueButton client from a domain that's different from where the BigBlueButton server is hosted isn't supported. You're probably going to hit a number of errors - it would be better if you can make the client load from https://domain2.com instead.

To solve the immediate error, you can adjust the nginx configuration on the BigBlueButton server (in the file /etc/bigbluebutton/nginx/web) to add an "Access-Control-Allow-Origin" header which permits access from domain1.com.

Calvin.

Hi  Calvin!

The error 1009 is solved but another error come: Now it display Error 1002: Could not make a WebSocket connection.

On Browser (chrome, firefox): i see a bug " ... can’t establish a connection to the server at wss://domain1.com/ws"

Do you have any suggest on this.

Thanks and regards

Hi Bin,

The URL used for the websocket connection is currently hardcoded to use the domain name that the client loads from. You might be able to change this by editing some of the Javascript code.

Hi  Calvin!

Thanks for your respone

I already change the url as you said, and the connection success. But it get another error: Detected the following WebRTC issue: Error 1004: Failure on call (reason=Incompatible SDP).

 Please help

Hi Bin,

I don't know if there's any way to work around this problem. Please use the freeswitch logs and JS console logs to troubleshoot, and make sure the IP address is configured correctly in the bigbluebutton server's "sip" nginx configuration file.

Hi Calvin!

I saw on freeswitch log and other but did not see anything error related to.

On Browser i got this information:

Hi Bin,

What happens when you connect to your BigBlueButton server using the existing API examples running on your BigBlueButton server?  Does it work?

Hi Fred!

I install BBB 1.1 on ubuntu and running the demo from Bigbluebutton everything is working( audio,video,webrtc...). I am developing a website (dotnet) that running on IIS( windows server)  to connect to BBB server from BBB API, it working with flash mode except webrtc for audio that the question i asked from begining of topic. 

i configure to run with cross domain like Calvin suggest then it work , but it seem to get another error 1002 Could not make a WebSocket connection, i also configure in webrtc_brigde to point direct to bbb server address. and websocket success connected . but now again it get another Error  Detected the following WebRTC issue: Error 1004: Failure on call (reason=Incompatible SDP) .

With this error i don't know how to figureout .

Could you check this situation and help me.

Thanks all of your support team.

This is the part that doesn't make sense -- if you can connect to the BigBlueButton server using the built-in API demos and the audio works then the BigBlueButton server is functioning correctly.

Next, if you are using your front-end application and generating similar API calls, it too should work.

You can test creating API calls using the excellent API Mate as well (enter the URL and shared secret for your BigBlueButton server).  See

  http://docs.bigbluebutton.org/dev/api.html#testing-api-calls

Can you try the above and let us know if it works without error.

Hi Bin,

You've hit a problem that I don't know the answer to, and since you're using an unsupported configuration, well...  let us know if you figure out a way to get it to work.

I strongly suggest that you find a way to serve the bigbluebutton client from the same domain name as the bigbluebutton server. This really shouldn't be too hard; in the worst case, you could just reverse-proxy your site behind the nginx on the bigbluebutton server.

Calvin.

Hi fred!

Thanks for your reply.

With my front-end on IIS i can create, join do everything exact the same bigbluebutton demo do without only webrtc audio that come with error. So no problem with API and BBB server is 100% functioning correctly. Maybe the configuration somewhere missmatch.

I will look at the link you gave and soon feedback to you.

 Thanks and regards

Hi Calvin!

Thanks you all for help. Since i am not family with opensource code, so i can not work front-end application on BBB server ( .Net right now does not play on opensource OS, Or i have to code it on ASP core 1 from Microsoft but it also limit) 

Could you do me a favour with this small test, you move your bbb client from bbb server to another server that also ubuntu/linux/readhat.. and connect to bbb server. If you hit the sam error i got so easy to find out, if not that is my big problem to find out.

Thanks and regards

Hi Bin,

Are you moving the 

  /var/www/bigbluebutton/client

directory to another computer?  You shouldn't do that -- leave that directory on the BigBlueButton server and use the API to join users on the BigBlueButton server.  The client will then load from the BigBlueButton server.

Regards,... Fred

Hi fred!

No i do not move, since  bigbluebutton/client  is the main core to run.

I tell Calvin is move the demo / front-end to another server, not running on the same server with BBB. Maybe my word make you guy missunderstand.

Hi Fred!

i forgot to open UDP port ( 16384 - 32768) on router that why i hit error 1004. But help me with Error 1007, i follow the installation guide  about to trace the error on firefox with column  Remote Candidate is correct external ip address or internal ip. 

On the log that column IP is correct .

The problem is my router does not allow udp packet through in both directions on the required ports. So how to configure this since i already forward UDP port as docs installation say.

Thanks and regards

Bin

[Fred Dixon]

Hi Bin,

> The problem is my router does not allow udp packet through in both directions on the required ports. So how to configure this since i already forward UDP port as docs installation say.

Not sure what router you have.  Check the documentation (and try using Google to find others that may have had similar problems with the same router).

Are you setting this up behind a residential router or in an external hosting service?

Hi Fred!

i running behind a residential router.

I removed my firewall checkpoint and direct connect server to modem TPLink that come from ISP. So do you have any document for that kind of router to configure??

One more think my server  running Symantec Enpoint Protection. Anything to do with this or not???

Thanks and regards

Bin

[Fred Dixon]

Hi Bin,

Recommend you check the documentation for TPLink router for configuration.  If the WebRTC calls still don't go through, try turning off the Symantec Endpoint Protection.

While such a setup is good to learn about BigBlueButton, we would certainly recommend you host your BigBlueButton server externally to your residential connection for production use.

Hi Fred!

I still got Error 1004, the day i reply to you it run when i open UDP port,but it happen again after 12hour. I don know what happen, even with bigbluebutton demo it running webrtc without open UDP port. but when i test to close upd port after open  bigbluebutton demo fail with webrtc :(.

I already check UDP port on both two server , that working well by using netcat command to test.

Before i hit 1004 i change two things with bbb_webrtc_bridge_sip.js

Change: var server = window.document.location.hostname;

To: var server = 'domain2.com';   ( domain2.com is bigbluebutton server)

And 

change:  url: '/bigbluebutton/api/stuns',

To:        url: 'https://domain2.com/bigbluebutton/api/stuns',

Since my front-end application running on difference domain and using .Net.

With debug i got error on this code:

$.ajax({

  dataType: 'json',

  //url: '/bigbluebutton/api/stuns',

                 url: 'https://domain2.com/bigbluebutton/api/stuns',

  data: {sessionToken:sessionToken}

  }).done(function(data) {

  var stunsConfig = {};

  stunsConfig['stunServers'] = ( data['stunServers'] ? data['stunServers'].map(function(data) {

  return data['url'];

  }) : [] );

  stunsConfig['turnServers'] = ( data['turnServers'] ? data['turnServers'].map(function(data) {

  return {

  'urls': data['url'],

  'username': data['username'],

  'password': data['password']

  };

  }) : [] );

  createUAWithStuns(username, server, callback, stunsConfig, makeCallFunc);

  }).fail(function(data, textStatus, errorThrown) {

  BBBLog.error("Could not fetch stun/turn servers", {error: textStatus, user: callerIdName, voiceBridge: conferenceVoiceBridge});

  callback({'status':'failed', 'errorcode': 1009});

It does not return value, it fail with message:(a)

 response:{returncode: "FAILED", respone message: "Could not find conference.", logoutURL: "https://domain2/com"}.

I test bbb-demo on bigbluebutton server it pass with respone message (b): {"stunServers":[{"url":"stun:stun.freeswitch.org"}],"turnServers":[]} 

I also test embed bbb_webrtc_bridge_sip.js code on front-end application but the same result . 

When i use json it fail with message like message (a). I change dataType: 'json', to dataType: 'jsonp',it return data like message (b) but i can not get that value to pass to .done(function(data) {.....}

Do you have any way/suggest to get value and pass it.

Thanks and regards

Bin

[Chad Pilkey]

You're really branching out beyond any sort of intended usage and that's why you're running into these issues. It's exactly as Calvin pointed out quite a few responses ago:

I strongly suggest that you find a way to serve the bigbluebutton client from the same domain name as the bigbluebutton server. This really shouldn't be too hard; in the worst case, you could just reverse-proxy your site behind the nginx on the bigbluebutton server.

Without a strong understanding of the different parts of the BigBlueButton server and client you're going to keep running into issues like these. It's also really hard to help when we can't see the full picture.

As to the error message you're receiving, the explanation is in the response message, "Could not find conference". The API call passes along the sessionToken and bbb-web tries to find conference information matching the Java Bean associated with your browser session. The sessionToken lookup is failing. It's either failing because of the domain the request is coming from or because "domain2" doesn't have information about your user.

Hi Chad!

I will make clear bigbluebutton first before going to next move with Webrtc.

Thanks and regards
