Cannot connect to host - Sagemcom F@st 5359 (KPN Box 12)

## Versions

| F@st Router Model | Sagemcom F@st 5359 |

## Describe the bug

Using the quickstart script I can't seem to set up a connection to my KPN Box 12 from my laptop.

The output:
`Cannot connect to host http:80 ssl:default [Name or service not known]`

I can ping the machine and get a reply back so it is reachable.

When I use only my IP address instead of http://192.168.2.254 I get an empty printed line(it still ends up in the client.login() Exception handler):


## To Reproduce

Steps to reproduce the behavior:

1. pip install this package and copy the quickstart script
2. fill in `http://192.168.2.254` as HOST(I've tried the IP without http:// as well and http://mymodem.kpn, didn't work either)
3. use "admin" as USERNAME and my admin's password as PASSWORD
4. tried both encryption methods, neither works even though it should be SHA512 according to the table
5. tried both with/without validating SSL cert
6. run the script
7. it runs into the connection exception while trying to client.login() and exits

## Expected behavior

I expected to connect to my KPN Box 12 and get my device info and connected devices and such.

## Screenshots



## Additional context

I'm wondering if it's not working because KPN recently rolled out their own KPN software instead of the slow "original" interface it had before that perhaps the calls or xpaths are different now, but I don't expect it.

[bug]

从 quickstart 脚本和 client.login() 调用开始，使用 Python 3.13.2、package 1.4.1 以及报告中的 KPN Box 12 详细信息重现该故障。确定连接失败是由主机处理方式还是路由器 API 行为发生变化导致的；当登录成功且能够获取设备信息时即表示完成。
