It is important to open up the firewall port for the connection to happen. If this is not done, you may experience connection issues as detailed below:

- The Customer reported a connection error.
- Sockets.IPPBX[0].Error: Connection to [\ ***** \]. Authoritative answer: Host not found. An attempt to reconnect will be made, but expect further errors.
- Data source "\ **** \" failed to connect to IP "https://****.ny.3cx.us/" at script line 1
- I have connectivity from the server to my PC. Software is installed on my PC. Server is in Azure.
Looking at the error message, it seems that the DNS is not able to resolve the address `****.ny.3cx.us`.
Can you try replacing the host name with the IP address which is currently `13.82.**.***` to see if that solves the problem?

I changed to the IP address before I sent the email (my mistake) and the result is the same. I’m using port 9000.
Any tool I can use to troubleshoot this issue? We have connectivity to the PBX because we copy recording files on a daily basis for archiving purposes.

Host and Port number
When using an Active connection (i.e. TIM Plus connects to your 3CX) remember to set the host and port numbers on the 3CX as follows:-

|---|---|---|

The host address drop-down contains a list of addresses that your 3CX can bind to. Choose one that will be accessible by the computer running TIM Plus. The port is the port that the 3CX will listen for connections on.
In the connection settings of TIM Plus, enter the address that your 3CX is bound to, as well as the same port you configured on your 3CX (above).

Firewall
Ensure that any firewalls on the 3CX and on the computer running TIM Plus allow traffic on the selected port.
In order to test whether the connection is working, use `telnet`:
| Code Block | ||
|---|---|---|

telnet 10.0.0.10 9000 |
If you don't have the Telnet client on your computer, could you try opening a command prompt and seeing if you get a connection through that?
`telnet 13.82.**.*** 9000`
If Telnet is not installed and you are not able to you can add it through the the Optional Features setting setting in Windows, there should be a tool called .
Failing that, TIM Plus comes with a stand-alone tool name `IPTester.exe` in your `c:\Program Files (x86)\Tri-Line\TIM Plus\` folder . If you run thatfor testing connections. Double-click to run it, enter the IP address and port at of your 3CX in the top left and press `Connect`. If it boxes and press
. If the application background turns yellow/green, then the connection was made OKsuccessful.Let me know how that works out.Buttonmacro Label Connect

This is the message I current get now.

6. Technical Support Response
Please let me know how it worked out with the IPTester tool.
If that cannot connect to your PBX, then TIM Plus won't be able to either.
Then you need to look at things like firewalls, IP restrictions, etc.
7. Customer response
I used the IPTester you suggested and found my problem. I had to open up the firewall port for the connection to happen.
SOLUTION: Once the firewall port was opened, the issue was resolved.
