Nextcloud Talk Federated Call

[CsYaKo]

Hello,

I have two Nextclouds running on AlmaLinux9.
Both are Federated. I can share documents and use Nextcloud Talk to chatt with federated user. I also can see the federated user.

My Problem ist how can I call someone with Nextcloud Talk?
Always one of them is connecting and the other user is "Waiting for others to join the call … "

server1.mydomain.com
server2.mydomain.com
and the coturn server are all in the same network without an Firewall

I have disabled the local firewall

I tried using a seperate server with coturn, but the problem remains the same.

first of all you need to enable federation call under Admin - settings - talk.

And then you should be able to establish a direct federated call to e.g. @userA@server2.mydomain.com if you are on server1.mydomain.com

I enabled it and I am able to join calls and i am able to chat with the federated user. but in the calls i think they do not fetch together, like you can see on the screenshot

[JimmyKater]

tbh I haven’t tried that feature myself, yet. (I tried federated talk-chats under NC and it worked like a charm)

but most likely it’s no bug but a setup problem. Hence we would need more infos about your server, serverenvironment, additional software, webserver, etc.

BTW: in this case I consider especially helpful if those two servers are on the same IP.

All the servers are AlmaLinux 9
I am running apache and php 8.2
Database is MariaDB

both nextclouds are hosted on a ProxmoxVE

my config.php is following:

[root@next01 ~]# cat /var/www/html/nextcloud/config/config.php
<?php
$CONFIG = array (
  'instanceid' => 'ocmq4lznzygd',
  'passwordsalt' => '***************',
  'secret' => '***************',
  'trusted_domains' =>
  array (
    0 => '10.12.*.*',
    1 => 'nextcloud01.mydomain.com',
  ),
  'datadirectory' => '/var/www/html/nextcloud/data',
  'dbtype' => 'mysql',
  'version' => '30.0.2.2',
  'overwrite.cli.url' => 'https://nextcloud01.mydomain.com',
  'overwriteprotocol' => 'https',
  'forcehttps' => true,
  'dbname' => 'nextcloud_db',
  'dbhost' => 'localhost',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'nextcloud_user',
  'dbpassword' => '***************',
  'installed' => true,
  'allow_local_remote_servers' => true,
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'maintenance' => false,
  'loglevel' => 1,

);

both nextcloud instances are in the same network with no firewall roules between.
Chat in nextcloud talk federated works well with no problem. I also dont get any log entrys when a call doesnt work.

[JimmyKater]

would you mind, giving me your fed-id as a PM so we could try it from outside your network?

[CsYaKo]

btw the servers are only for internal use…they are not reachable from outside

[JimmyKater]

That’s ok. In general.

But at the same time that might be the problem.

[CsYaKo]

I sometimes get following error in my Nextcloud log:

CannotReachRemoteException
cURL error 28: Operation timed out after 5001 milliseconds with 0 bytes received (see libcurl - Error Codes) for https://nextcloud01.mydomain.com/nextcloud/ocs/v2.php/apps/spreed/api/v4/room/ef5vn6mp/federation/active
Could not reach remote

I can ping server01 to server02
and also from server01 to server01

DNS resolution also works

[JimmyKater]

I think it rather might has to do with selfsigned certificates

[SysKeeper]

Indeed both servers need to trust each other.
On the other hand, you should also check if the server didn’t brute force protect each other …
