Suddenly HA loosing connection (and all integrations) fron fritzbox

[medicus21]

The problem

Hi there

I'm already facing this problem the second time: Suddenly without having changed anything Home Assistant starts to display the following error when trying to connect to ny Fritzbox 5490:

HTTPConnectionPool(host='192.168.178.1', port=80): Max retries exceeded with url: /login_sid.lua?version=2 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fb2367f1e50>: Failed to establish a new connection: [Errno 113] Host is unreachable'))

Therefore a lot of tools are dispalyed as offline/not reachable.

I already tried to reload the integration for AVM Fritz! Smart Home as well as restartet HA and the fritzbox as well - without any effect.

The Shellys are all displayed without any problem directly through the Shelly App and are working fine.

Can you help me with this problem?

thanks a lot!

Homeassistant web app is not loading anymore in the browser... What could be the problem?

It just happened again after I succeeded in running HA since opening this issue. Last time I restartet Fritzbox several times until it suddenly worked again.. but this morning out of nowhere it lost connection to every device (again). In the shelly app as well as using the device ip directly the devices are all online and available...

Is there anything I can do to get a stable connection beweteen HA and my fritzbox integration?
