IP Address provided (xxx.xxx.xxx.xxx) invalid

[Ferkelcode]

Hello,

I tried bacnet = BAC0.connect(ip='xxx.xxx.xxx.xxx')

but it shows: BAC0.core.io.IOExceptions.InitializationError: IP Address provided (xxx.xxx.xxx.xxx) invalid. Check if another software is using port 47808 on this network interface. If so, you can define multiple IP per interface. Or specify another IP using BAC0.lite(ip='IP/mask')

Do you know what could be the reason?

I got 2 IP addresses (xxx.xxx.xxx.x47 and xxx.xxx.xxx.x48), I only know that one of them is correct for the device. But I tried both of them with bacnet = BAC0.connect(ip='xxx.xxx.xxx.xxx').

For xxx.xxx.xxx.x47, it shows: 2022-10-09 13:41:24,798 - INFO | Starting BAC0 version 21.12.03 (Complete) 2022-10-09 13:41:24,798 - INFO | Use BAC0.log_level to adjust verbosity of the app. 2022-10-09 13:41:24,798 - INFO | Ex.

For xxx.xxx.xxx.x48, it shows:

Can I say that xxx.xxx.xxx.x47 is the correct IP for the device, but there is another software using port 47808, so I cannot connect? And why the IP changed from xxx.xxx.xxx.x47 to xxx.xxx.xxx.39?

Thank you very much.
