The integration suddenly stopped working

[Legende04]

I started my pc a random day and it cant connect to home assistant anymore. I used to have the link http://192.168.../8123 which does not work anymore
then I changed it to ws://192... that worked for a short period of time, but now also fails
the I tried ws://192.../api/websocket, that did not work at all
I already checked if my home assistant is on, the ip adress is right, port is the right, so i don't know how to fix that, besides that, awesome plugin guys, thank you
plugin version 3.7.0.53
elgato version 6.8.1

and what I did not try is to reinstall the plugin, because i fear losing all my buttons, can i reinstall without losing them?
