Talk HPB opening a conversation Error while creating the conversation

Nextcloud talk server 19.00 ubuntu 18.04 cloud.example.net
HPB signaling server (Nats, Janus, Signaling, apache2) ubunut 20.04 signal.example.net
Turnserver (Coturn) ubuntu 18.04 turnserver.example.net

I downloaded Nats-io from here:
Nats
unzipped it, copied nats-server to /usr/bin.
I start it manual in terminal window > nats-server -c /etc/signaling/gnats.conf (as regular user)
Nats-io has never logged anything, however signaling server finds it.

I installed janus
sudo apt-get janus

I installed signaling server supplied by @morph027 (thanks for that)

Everything seems right except it doesn’t create a conversation.

Error while creating conversation.

How to troubleshoot?

I am not that familiar with Janus or Signaling, so not really sure what success looks like. The signaling server seems to find the nats-server and janus videoroom, websockets seem like them are accessible to signaling server. I am not getting complaints about the SSL certs.

There is an exception at the top of the nextcloud log, complaining about expecting a string.

Not really sure how to troubleshoot from here. Any suggestions would be appreciated.

thanks

There seems to be an issue with your nextcloud config in the admin interface of talk.

3

Thanks so much for the response.

Talk works when the HPB entry is removed.

I left the stun server as the default:
stun.nextcloud.com:443
I did not configure a stun server in the signaling server.

I left my turnserver configured as before I added signaling server.
turnserver.example.com
I configured the signaling server to point to my turnserver.

How should i address the signaling server in the talk admin.
I have tried:

signal.example.com
returns OK: Running Version:

signal.example.com:443
returns Error: Server responded with 400

http:signal.example.com
returns OK: Running version:

https:signal.example.com
returns OK: Running version:

http://signal.example.com
return Error: Server responded with 404

http://signal.example.com:443 (included to show all possibilities)
return Error responded with 400

https://signal.example.com
returns Error: Server responded with 404

https://signal.example.com:443
returns Error: server responded with 404

ws:signal.example.com
returns OK: Running version:

ws://signal.example.com
return Error: Server responded with 404

all four that return OK: Running version
Also Error while creating the conversation.

thanks
@Stevebrudi

Try wss://signal.example.com

Nick
I really appreciate your input thanks so much.

wss://signal.example.com
returns Error: Server responded with 404

wss:signal.example.com
returns OK:Running version:

Error while creating the conversation

6

Update:
wss://signal.example.com
returns Error: Server responded with 404

I tried creating the conversation while admin page displayed the error message, it worked, conversation created.

an initial attempt to start a call, failed to establish a connection to the signaling server.
tried again, this time no complaints about connections.
then attempted start a call again is now waiting others.

Error while creating the conversation is resolved, thanks so much. A misleading error msg.

7

Update2
It was not a misleading error code. the OK message never completed.
the apache2 rewrite rule used /standalone-signaling/ to determine which request to forward.

wss://signal.example.com/standalone-signaling/
returns OK: Running version:
a number in hex is displayed.

Hi … I have a similar problem …
On my server install Nextcloud 19.0.2, Talk 9.0.3, Ubuntu server 20.04, Nginx, PHP 7.4, etc … domain cloud.example.com
In VPS install Nginx, HPB Signaling Server (Nats, Janus, Signaling, coturn) signaling.example.com
Turnserver (Coturn) turn.example.com

Without HPB Signaling Server communications can be established, as soon as I configure the server in nextcloud, communications are not established …

This is the Nextcloud log:

Hi!
I’m dealing with the same issue as your wrote.
In my case it is a matter of the backend config in the server.conf of the signaling server.
As soon as I set “allowall = true” the connection works instead of the 403 error.
(Although I think that I configured the backend right without using allowall, it did not work…could not find out why yet).

Although my setup does not work completely yet, I at least got beyond this problem :wink:
Hope this helps.
