V20 behind IIS

[FireManager]

Hello,
im New in this Forum....
I will Host on Prem 3CX behind an IIS Reverse Proxy.
The Admin Interface --> Firewall ist green an test is ok.

Aktuell 1 have to Things not working
--> The APP is not loading the User Status and Phonebook ist on loding....
--> The Konferenz in the 3CX "3cx..... hat dich zu oft weitergeleitet."

Gibt es für IIS eine Muster Konfiguration ? Websocket ist aktiviert.
Gerne stelle ich meine aktuelle zur Verfügung.

Gruß Michael

It's not supported to host 3CX behind a proxy.

But not connected usually points to a secure websocket not being proxied (wss:// protocol).

We need to run it on Proxy.... i think, im not allone.

Just use a different https port for 3cx

 

[FireManager]

OK... maybe possible.
I have seen, in the Config File, there ist set a part HTTPS with Port 443
Can I change this Port without reinstall ?

No, you need to reinstall. But backup and restore ist fast. You can change the port in the config before you upload it to the pbx during install.

 

[FireManager]

yes... done reinstall with alternative Ports ... looks like working.... we will test
