Warning: Failed to verify STUN server

[TS]

Hello,

I installed BBB 2.3 with the install.sh  and API demos. This installation was only to test the new version 2.3.

We have already a BBB-Cluster with BBB 2.2, scalelite, greenlight and TURN-Server.

From that existing  installation I copied the turn-stun-servers.xml to the "old" path, later also to /etc/bigbluebutton. After a bbb-conf --restart there is an error message

# Warning: Failed to verify STUN server at  3478 with command

# stunclient --mode full --localport 30000  3478

It seems like my stun/turn-server-configuration is not recognized.

thanks

Same Problem with BBB 2.3.1

When I use the original turn-stun-servers.xml with STUN-Server "stun:stun.l.google.com:19302", no error is thrown when I restart BBB.

But firefox can't initialize the audio, the echo-test fails with error 1007, when I set  "media.peerconnection.ice.relay_only = true" to force

firefox to use the TURN-server.

Turn is not stun.

Is coturn running on correct ports?

You can check it with:

ss -tulpn |grep turnserver

[TS]

> Turn is not stun.

My fault, both services run on the same server, so I mixed the words.

> Is coturn running on correct ports?

> ss -tulpn |grep turnserver

I think so. We have 2 stun/turn-servers, which are "included" in a BBB 2.2 cluster with scalelite. This works fine.

Your command gives a lot of open ports, tcp 3478, tcp 443 and many udp ports.

But when I copy the turn-stun-servers.xml from one of this BBB-2.2-server to the single BBB-2.3-server, installed with install.sh,

then the mentioned error comes.

The command suggested in the error "stunclient --mode full --localport 30000  3478" I think is strange.

Between the 2 ports the name of the server is missing. Does this mean, BBB could not read the servers name from the config

or is it just an output-thing

[Philipp Memmel]

For me this looks like a wrong configuration in the
turn-stun-servers.xml or maybe even a working configuration which isn't
correctly parsed by bbb-conf. Can you maybe post yours?

My first guess would be that you didn't put a "stun://" before your stun
server's hostname in the turn-stun-servers.xml? Can you doublecheck?

[TS]

The format is like it is listed here

https://docs.bigbluebutton.org/2.2/setup-turn-server.html#configure-bigbluebutton-to-use-your-turn-server

There is also no double-slash before the server. But I also tried with double-slash, but without success

[Philipp Memmel]

Sorry, I didn't want to add the double-slashes of course.

You only could take a look at the corresponding lines in
/usr/bin/bbb-conf and try to figure out which line exactly is causing
this error and why it's doing that in your specific
turn-stun-servers.xml configuration.

Thank you for the hint to take a look in the /usr/bin/bbb-conf

It works when I define only one stun-server in the file turn-stun-servers.xml . The script /usr/bin/bbb-conf is not able to read more than one stun-server

This must be a bug.

There is a variable $STUN which has the value "stun1stun2 " when I have 2 stun-server configured. But this is not working, because

this variable is then used as an index :   id=\"$STUN\"]

Dont know,, if this also happens, when there are more than one turn-server is configured.

Hi,

If you are running your CoTurn local NET then be sure to add it to your /etc/hosts file.

When receiving: Failed to verify STUN server at 172.217.212.127:19302

I change STUN server to 3CX (or your favorite STUN)

/etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini

stunServerAddress=54.37.20.144

stunServerPort=3478

and here: 

/opt/freeswitch/conf/vars.xml

 <X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.3cx.com:3478"/>

<X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.3cx.com:3478"/>
