Only internal calls possible

Hi @mniehren,

that sounds like you are either missing a Turn server, or your turn server is not properly configured.

Hi Felix,

after more check’s i can say, the turnserver is ok and it run’s. Only some client’s doesn’t work:

• with Firefox everything works under Windows, Linux, Android 9 and Android 10
  • 1 hint under Android 9 (Lineageos) with Firefox 68.8.0 and Chrome: there is no green button to start a call
    or create an new group, is this a known issue ?
• with Google Chrome no connection is established. I tried under Android 9 and 10, also with
  the current version 81.0.4044.138
• with the Vivaldi Browser under Linux will also no connection be established

best regards,
Michael

How have you configured your system/turn server?

If you have a subscription it may be a good idea to reach out to our support so that we can check directly on your system.

@fbartels

here is my turnserver.conf:

server-name=kopanotest.tuxlan.de
realm=kopanotest.tuxlan.de
cert=/etc/tuxlan/keys/public_tuxlan.pem
pkey=/etc/tuxlan/keys/key_tuxlan.pem
fingerprint
listening-ip=0.0.0.0
listening-port=3478
tls-listening-port=5349
use-auth-secret
static-auth-secret=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
cipher-list=“DEFAULT”
no-multicast-peers
min-port=32355
max-port=65535

I’ve create 3 account’s for you: kopano1, kopano2, kopano3, the passwords are the same as the account name

The server is reachable under https://kopanotest.tuxlan.de/meet

Webapp does currently not work, i am playing with OIDC for single sign on …

best regards,
Michael

@mniehren and what have you configured in kwmserver for it?

[mniehren]

@fbartels

here is my kwmserver.cfg:

oidc_issuer_identifier = https://kopanotest.tuxlan.de
insecure = no
enable_guest_api = yes
registration_conf = /etc/kopano/konnectd-identifier-registration.yaml
turn_uris = turn:kopanotest.tuxlan.de:5349?transport=tcp
turn_server_shared_secret = /etc/turnserver.secret
public_guest_access_regexp = ^group/public/.*

@fbartels

if your support need root access over ssh, send me the public key to michael@niehren.de

@mniehren said in Only internal calls possible:

turn_uris = turn:kopanotest.tuxlan.de:5349?transport=tcp

There are two issues on this line:

1. you are using the tls port of turn, but classify it as non-tls in the url (turn: instead of turns:)
2. but: most browsers do not fully support turns, so its recommended to use a non tls connection to the server.

[mniehren]

@fbartels

so it’s better to take turn with port 3478 for all browsers ?

[fbartels]

@mniehren yes

Edit: well it does not have to be this port, but simply the non-tls port of your turn. To raise the chance to get connections on public hotspots you should actually make your turn listen on port 443.

[mniehren]

ok, i open the port 3847/tcp on the firewall, change the config to
turn_uris = turn:kopanotest.tuxlan.de:3478?transport=tcp
and restart kwmserverd

but i still got no connection with Chrome

[mniehren]

@fbartels

Port 443 is handled by kwebd. It’s all on the same server.

[fbartels]

@mniehren said in Only internal calls possible:

3847/tcp on the firewall

Typo?

If it still does not work I recommend again to get in direct contact with our support: https://kopano.com/support-info/

[mniehren]

@fbartels

i mean port 3478/tcp

[mniehren]

Hi Felix,

i found the error. I forgot to open the firewall for the turnserver UDP Port’s. Now,
everything is runnig :-)). Many thanks for your help.
