[jitsi-users] "Error: Could not establish connection (ICE failed)"


#1

Hi,

a friend and I have created Jitsi accounts a couple of days ago, and yesterday we tried to have a video chat. However, once the receiving person accepted the call, he/I got the message "Error: Could not establish connection (ICE failed)".

I have read a couple of messages from this archive. It was often asked whether both parties used Jitsi XMPP accounts, which either of us do. Sometimes it was suggested to change some ICE settings, but, frankly, I cannot find the place to do that in the "Options" menu.

Any help would be greatly appreciated. Please be aware that I'm a newbie, so if you suggest to change certain settings or so, please describe in at least some detail how to do that.

Kind regards
Thorsten

Same here.

whether both parties used Jitsi XMPP accounts, which either of us do.
Sometimes it was suggested to change some ICE settings, but, frankly, I
cannot find the place to do that in the "Options" menu.

The ICE settings are on a tab under for the specific account settings.

I have not had success by changing them though.
Is one of your routers of the "fritzbox" type? I am wondering what type of
NAT (symetric, open/restricted/... cone) these boxes implement.

PS: A zipped log file is attached.

Could somebody tell us or point to how pcap files can be viewed?

The logs show that all connections, including the ones to the to the
jit.si relay, fail. This probably means that there is an overly
restrictive firewall somewhere.

https://jitsi.org/faq/ice-failed could probably shed some light into this.

Hope it helps,

Hi!

I have read a couple of messages from this archive. It was often
asked whether both parties used Jitsi XMPP accounts, which either
of us do. Sometimes it was suggested to change some ICE settings,
but, frankly, I cannot find the place to do that in the "Options"
menu.

The ICE settings are on a tab under for the specific account
settings.

I have not had success by changing them though.

For me, I could solve the problem by using a TURN server. I run it on
my VPS, and when I point Jitsi (on both sides) to this server, it
works. However, it is clear that this is not a solution for everyone
- -- only those who actually have a server where they can run the TURN
server on.

I have no idea how else this can be tackled or whether there are free
TURN servers out there to use. I was happy with that solution and
thus didn't look further (took me long enough to figure it out).

If you happen to have a server available where you could run TURN, I
can provide more details how I did it. But note that I'm not a Jitsi
developer or even expert in those matters.

Yours,
Daniel

Boris,

thanks for checking the log file. I tried to connect from my workplace, so there may indeed be a restrictive firewall. However, Skype video chats work fine. Also, text messaging via Jitsi was not a problem - whether that means anything regarding the video chat problems, I have no clue.

You did not mention any remedy - simply because there is none you know of?

Regards
Thorsten

Hi Emil,

thanks for the hint. When I video chat with may friend from home, it works just fine. From my office however, it won't work, so the situation you describe in the FAQ entry may well apply here, I don't know.

However, Skype video chat works fine from my office - apparantly they must be doing something differently, and I'm wondering whether you guys have an idea what that might be and whether it would be implementable in Jitsi?

(This guy with the address ca2013@arcor.de put forward an idea in a mail from February 14th that noone responded to, really, I believe?)

Kind regards
Thorsten

That's correct. For audio/video to work in Jitsi, it is required that
UDP is allowed.

I don't know, maybe the skype remedy is to fall back to TCP and use port 80 for their
relay servers?

I found jitsi to be the best alternative there is today, for the average user.
Hopefully with such additional tweaks it is possible to reach the same
reliability with relay servers.

(And also without relay servers through some additional local (port forwarding)
configuration.)

Chris
