No data transfer between Fritzbox and homebridge
**Describe the bug**
A clear and concise description of what the bug is.

For about an half year the installation was running normal.
I‘m not using the functions of the homebridge every day.
Now I observed since the update of the plugin to 6.0.10, there is no communication any more between Fritzbox and homebridge for smart home units of AVM.
All other devices from other solutions like Shelly are running normal.

If you are looking into the plugin settings, you think, where are the settings? You can only see and set the settings by the json configuration file. 

On the homebridge protocol, you can see the communication. Shellys and other solutions are transfer data or status, but no data or status of fritz/avm units. 

On Fritzbox, there is the version 7.2.7 running. 
As well, I tried to make the latest updates for the homebridge via ssh. 
As well, I tried older versions of the plugin like 5.12. no help.

**To Reproduce**
Steps to reproduce the behavior:

This configuration stays on.

**Expected behavior**
A clear and concise description of what you expected to happen.

Maybe the company AVM has changed the rules for reading and setting data for smart home on the last updates. Since 7.25 you have to have an user name with a password.
