Problem with WebRTC connection on iOS

[rickKoch]

I'm using the web sdk and I'm trying to connect iPhone with the WCS but I have this issue:
WSServerHandler - WSS-pool-23-thread-1 THIS DOMAIN IS NOT ALLOWED origin: app://localhost allow: null

I tried with origin null, but also got this:
WSServerHandler - WSS-pool-23-thread-1 THIS DOMAIN IS NOT ALLOWED origin: null allow: null

Can you please help me with this

Hello

How exactly do you test? Could you please provide a screenshot.

From this demo page we were able to connect using iPhone and iOS 14 Safari browser

Two-way Streaming

Server version 5.2.971

 

[rickKoch]

It's a hybrid application with Cordova, and we are using web sdk. So it's using safari in the background.

It's working fine with Android application.

Add this line to /usr/local/FlashphonerWebCallServer/conf/flashphoner.properties

allow_domains=app://localhost

and then restart service

service webcallserver restart

I got this now:
WSServerHandler - WSS-pool-23-thread-1 Orgign: app://localhost
DomainChecker - WSS-pool-23-thread-1 Can't parse origin as URL app://localhost
WSServerHandler - WSS-pool-23-thread-1 THIS DOMAIN IS NOT ALLOWED origin: app://localhost allow: app://localhost

WCS server can't parse passed origin: app://localhost
In current implementation, origin should be either

1) Empty (as sent from Android SDK and iOS SDK)

2) Valid URL, i.e. https://mycompany.com/page1.html or file://myapp

https://www.ietf.org/rfc/rfc2396.txt

We raised internal ticket WCS-3219 to fix that.

Meanwhile you can avoid this error using nginx as a reverse proxy for Websocket protocol.

Example:

You connect to nginx wss://mydomain.com:443
Nginx proxies this connection to ws://localhost:8081 or wss://localhost:8443
Therefore you will be able to remove Origin header.

Good day.
We fixed the issue with app://localhost origin in build 5.2.995. Please update and check.

Hello!
I found this thread accidently. Does this mean that the WebSDK meanwhile is working on an iPhone? Some time ago that was still not possible due to restricted websockets/webrtc support.
I need it as a low latency audio only streaming.

Best regards
Marc

Does this mean that the WebSDK meanwhile is working on an iPhone?

Yes, WebSDK works in iOS Safari browser since iOS 12. Additionally, WKVebview supports WebRTC since iOS 14.3 (we've teste this on iOS 14.5 and newer), so in iOS 14 WebRTC is also available in third party browsers (Chrome, Firefox), but they all have Safari under the hood.

Damn, that is fantastic! I thank you very much!

If you're using AWS Marketplace image, you can update WCS on the instance manuall as described here.

HI @Max , I was able to update the server, and the connection is also established, but the video is not displaying. It is also able to give a callback of playing. this only happens in iOS

Please check if the issue is reproducing in Two Way Streaming example (you can test it from your server on webpage https://server:8888/client2/examples/demo/streaming/two_way_streaming/two_way_streaming.html). If not, modify this example code minimally to reproduce the issue and send the code using this form
If you are using some framework, please test Two Way Streaming React example or Two Way Streaming Typescript example.
If you're testing in iOS 15.1, there can be Safari bugleading to page crash. please read here (p. 17).
If the problem is reproducing in Two Way Streaming example, collect a report as described here and send using this form

Hi I tested the Two Way Streaming Typescript example and its not working on iOS. It is not showing any error while playing or while connecting and is showing just a blank thing. Please not this only happens on iOS

Please clarify what iOS version do you test? The example seems to be working correctly (publish and play) on iOS 14.7.1 and iOS 14.8.
