I am trying to get coturn working on my vps provider (I am using digital ocean) for matrix rtc.

I cannot seem to get matrix dendrite to connect to it. I think I have landed on the issue being dns records in cloudflare but I am unsure. Recently I switched to cloudflare and have been using tunnels (which I use for matrix)

Matrix dendrite works fine besides rtc when I uncomment the lines for the turn server but then doesn't function at all when they are there.

I am using ubuntu with docker for matrix dendrite and I am using a debian vps with digital ocean for the coturn server.

Any help is appreciated!

EDIT: Lemmy you beautiful community you!!! Solved yet another issue of mine!

Have you checked your coturn server works correctly? And answers requests in the first place?

See if you get some lines with type "srflx" or "relay".

(And I believe coturn needs to bypass cloudflare. Unless you have an enterprise subscription, it doesn't do raw TCP/UDP connections. So TURN can't work through a free cloudflare tunnel. You need ports 3478, ... and port-min to port-max open on your VPS. And DNS (at least for coturn's subdomain) point to the correct IP of your VPS.)

So I checked and I do not think it can connect.

I have a cloudflare domain I am using and I am only using cloudflare tunnels for the matrix dendrite server not the coturn vps server. I am using cloudflare to setup dns record for coturn on my purchased domain. Is that still an issue?

EDIT:

so i just tried it with the regular vps ip address instead of the domain I set in the dns records and the test tools you linked say it is working that way.

Make sure cloudflare proxy is disabled on that DNS record.

Just barely fixed that! Thanks! I have another issue thst I fommented about though:

Progress has been made!

So I got it working with the domain name. The turn testing tools now respond with relay and pin point the vps server! Nice!

However when I put the info into the matrix dendrite.yaml it still crashes. The logs say

"Invalid config file: yaml: line 210: did not find expected key"

"Invalid config file: yaml: line 206: did not find expected " - " indicator"

Line 210 and 206 refer to the turn section which is formatted:

turn: turn_user_lifetime: "5m" turn_uris: - turn:turn.exampledomain.com?transport=udp - turn:turn.exampledomain.com?transport=tcp

turn_username: user
turn_password: password

Throw the whole thing into a YAML linter: https://www.yamllint.com/ and see what it says. Likely a spacing/indent format error or something like that.
