Hello,

I’m having difficulties with timeouts on iOS/macOS clients trying to join an audio conference with the effect that some clients can’t ever connect. Turnservers as well as BBB-backend have been set up using bbb-install, all have a decent network connection.

I also tried to only use turn, not turns, for the turn server connection to rule out tls / certificate problems but with no effect.

Here’s a log from safari trying to connect:

These are some measurements from the same user with different machines, some via wifi, some via ethernet cable from the same DSL line:

1) MAC-Safari/Chrome wifi ->Timeout after 20 sec / on 3rd try 18 sec ACK from Server and connect

2) MAC-Safari/Chrome wifi -> on FritzBox mesh net on another floor in the house via 3 internal hops (2xRepeater, 1x FB) -> 9 timest timeout after 25-35 sec / one time connection after 19 sec

3) MAC-Safari/Chrome LAN -> no Timeout / 1 attempt 14 sec ACK from Server and connection -> 3 more tests with times between 12-19 sec

4) IPAD pro Safari and wifi only -> without hops directly on Mesh at FB / 3 Timeouts after 22-35 sec / 3 connections after 18-20 sec

5) IPAD pro Safari and wifi only -> with 2 Hops / 5 Timeouts after 22-35 sec / 1 succesful connection after almost 20 sec

6) Windows10 PC wifi with Chrome 3 Hops after 22-30sec always succesful connection

7) virtual machine with Win10 and chrome on MAC same results as in 6)

Connection attempts via LTE didn’t suffer from the problem.

So it seems the problem is with the ice connection negotiation timeout in certain network topologies. What I don’t understand is why windows clients don’t seem to be affected from the timeout, even when it takes more than 20s.

Is there anything I can do to improve the situation? Can the timeout setting be raised without having to recompile the bbb-html5-client?

Thanks for your thoughts: Jan.

Hi Jan,

To cross-check could you try https://test.bigbluebutton.org/ and let us know if you encounter the same timeouts there as well.

Regards,... Fred

Hi Fred,

sorry, I forgot to mention, with https://test.bigbluebutton.org everything works like a charm.. Do you happen to know about the exact settings used there?

Thanks & Best: Jan.

Hi,

I finally raised

CALL_CONNECT_TIMEOUT = 60000;

ICE_NEGOTIATION_TIMEOUT = 60000;

and compiled bigbluebutton-html5.

With those settings the clients in question were able to establish a connection without problems. Could those settings be made available for configuration or raised per default?

Best: Jan.
