I've sent an email to support@disroot.org. I'am copying to here for better tracking. PCAP files omitted for privacy reasons.

Disroot.org admin,

I’m reporting turn:disroot.org:3478 for XMPP calls dysfunctional.

I was trying to call another user on XMPP client Conversations and it always fails.

I tried to diagnose with PCAPDroid and found that there are only direct connection attempts to the other party’s IP address. But on another server movim.eu, I saw the call data is relayed through a Germany netcup IP address (relay allocated from TURN server).

At the packet capture (see attached pcap files), for Movim, I can see the TURN server responded with,

Allocate Success Response XOR-MAPPED-ADDRESS: xx.xx.xx.xx:58427 XOR-RELAYED-ADDRESS: 94.16.111.188:59349 lifetime: 600

Then data is relayed through 94.16.111.188:59349.

But for Disroot’s TURN server, it doesn’t respond to Allocate Request at all, only responding to Binding Request.

From attached 1.png, You can see a lot of Allocate Request but Disroot responded none of them.

Thanks for posting. I was plannig to look into this week but have had other priorities. I will try to prioritize as it affects more people that require turn. 8817977
