TP-Link Deco integration in HA - problem connecting

Dear all,

Unfortunately, I couldn’t find anything using the search function, and even Google and the integration documentation didn’t help me:

I have installed Home Assistant on a Raspberry Pi as a newbie and would like to control the devices on my TP-Link Deco routers via the HACS integration - among other things to be able to assign them to persons.

Unfortunately, I am already failing to connect to my router (Deco X50) after installing the integration.

I get the error message “unable to connect to host” in the mask where I have to enter host, username and password, etc., although it is 100% the correct host IP (192.168.68.1), even a https:// in front of it does not help. With the browser I can call up the admin panel with this IP without any problems.

Is there anyone here who could help me?
