Why does matrix docker not open ports needed for turn server?

[nebulon]

Since the turn server exposes a port range 50000-51000/udp it runs on the host interface directly. You should see the firewall settings with iptables -L and then for the turn server this section:

ACCEPT     tcp  --  anywhere             anywhere             multiport dports 3478,5349
ACCEPT     udp  --  anywhere             anywhere             multiport dports 3478,5349
ACCEPT     udp  --  anywhere             anywhere             multiport dports 50000:51000

video and phone calling has not worked for anyone using cloudron

I've not tried it for a while, but when video calling first came out I gave it a try and it worked fine with a 1 to 1 call (not tried a group, which I guess is where the turn server comes in)

[danielreyes61]

@jdaviescoates it works fine when both parties are on the same network.

[jdaviescoates]

@danielreyes61 my 1 to 1 call didn't involve people on the same network, but I guess maybe it was in p2p mode like how Jitsi works p2p when 1 to 1 too ‍️ but I'm just guessing and it was a while ago.

[danielreyes61]

@jdaviescoates interesting. I wonder if it's working for others now? I feel like i've tried everything.

[jdaviescoates]

@danielreyes61 shall we see if it's still working for me? https://matrix.to/#/@josef:uniteddiversity.coop

@danielreyes61 it does if all the network plumbing to all the parties is working. You'd have to test both tcp and udp connectivity as those are separate audio and video channels.

It's also not always a Cloudron side issue, as clients have misconfigured routers too.

[danielreyes61]

@jdaviescoates sure, trying now!

@jdaviescoates tried to join and send message, it says Messages failed to send, do i need to be federated or anything?

[danielreyes61]

@nebulon ok I see them now, thank you. It must be an issue with my host then. Oracle Cloud Free Tier.

TBH I'm not sure, but I'm not seeing any requests to chat at my end

[danielreyes61]

@jdaviescoates ok no worries. thanks for trying!! I'm not too sure either. All good though. Pretty sure the issue is with my host. May try some other things locally to test to be sure. Thanks!

@danielreyes61 tried but I didn't see anything at my end. Perhaps anyone else reading this could give it a try (just to reassure me it is working at my end ) @robi ?

@jdaviescoates sent you a note and it went through

No fear.

[jdaviescoates]

@robi thanks

@danielreyes61 maybe worth looking at the ICE handling on your browser side which potential routes it proposes. At least firefox has about:webrtc to get more info.

[danielreyes61]

@nebulon what is ice handling?
