Port Forwardin, internet?

I activated the internal XMPP which is fully enough for my setup. In my LAN I see a list of contacts and the online state of those contacts in the sidebar.
If I access my server from an external Network (internet), this is not working. In the internet I get notifications and I can send chat messages, but I donot see a list of contacts + online state.
Is there specific ports which I have to forward?
best regards

No, you don’t need any port forwarding for the internal backend. Can you check your javascript console for errors?

I did both :wink:
With forwarding enable it still does not work in the internet but local it does.
In the console there is no error:

But there is no error

The console looks good, so I don’t have a glue why this is not working. Can you maybe send some test credentials to klaus@jsxc.org?

I sent you but my mail tells me that message cannot be delivered.
Did you still receive the testcredentials?
BTW: My Server runs on a non default port from outside, maybe thats why?

I received your mail, but you forgot to tell me your url. :wink:

ah OK :wink:
I send you per Mail as well :wink:

you got it?

Nope, but maybe you want to send it as pm.

Can you send me an pm that I can answer it?
best regards

You can test forwarded ports using Port Checker website.
