Error ICE 1007 on Wifi network

[Specialized Solutions]

Good day everyone,

I installed BBB version 2.5.6 on Ubuntu 20.04 on gCloud using the installation script and added GreenLight to it. It went very smooth and quick, then logged in.

audio selection.jpgWhen I wanted to connect, it was asking to join an audio, then when trying to use a micorphone it gives an "error ICE 1007".

This happens when I am using wifi behind a router, while if connecting using mobile data, it connects well without any problems.

What would I do to make it always work?

Thanks for your help,

[Fred Dixon]

Try using FireFox and then when you get the error, open a new tab and visit `about:webrtc`.  This will tell you the IP addresses that your browser and the server are exchanging as candidates for connectivity.

Try in both scenarios and see what the difference is in IP addresses.  It may be that your router has a built-in firewall that is preventing UDP connections, which is the source of the 1007 error.

Thanks Fred for your answer. I will download firefox and check it again.

On the other hand, I am using chrome on both the desktop and mobile and in both it does not work on wifi network, but when I tested https://test25.bigbluebutton.org, it is working completely fine in both desktop and mobile being on the same wifi network that was used to connect to my server.

Is there anything that is making the difference here? Is there anything that could be done on the server side. I have the assumption that there is something preventing it on gcloud, but when using mobile data, it works fine.

I will test again and get back to you. I can provide the url to the server if necessary. 

Best regards,

Thanks again Fred. Your message actually brought to my attention about UDP, so when I checked the server for that it was clear that it is not open by default, so once it is allowed, audio connection is working fine now.
