Stuck on unable to connect to homeassistant after installing new dashboard from hacs

So basically, i wanted to make a new dashboard so i installed the mushroom auto dashboard generator from hacs.
It generated a new dashboard for me and everything seemed fine, i then noticed that i couldnt connect to homeassistant on my phone, so i restarted homeassistant. and after that i just keep getting the unable to connect to homeassistant.
I can connect via ssh and i can acces my ha files and automations and all that works, websocket dosent work tough.

I hope that someone can help.
