Bad request

I’m now having the same issue. I don’t want to downgrade too far after the database changes. Let me know if you come up with a fix for this.

Oddly enough, I noticed that commands to the foscam camera were failing in the console. I restarted my camera and hass and I have my front end back again.

I have not fixed my HA. I am using Old version of HA. I am planing make some gasket from my ZigBee to MQTT

I had the same problem, I fixed it by editing my configuration.yaml and surrounding the path to the pen files in single '. So yours would look like:

ssl_certificate: ‘/etc/letsencrypt/live/xxxx.ddns.ukrtel.net/fullchain.pem’
ssl_key: ‘/etc/letsencrypt/live/xxxx.ddns.ukrtel.net/privkey.pem’

Hi.
Thank you for answer. Certificates does not meter. It does not work without any certificates.

Hello, same problem here. Once from nothing I was not able to open page, tried restart and from then it is not working. I searched log the first exception occurs after trying to install cherrypi library. But system stopped working out of nothing, I was not changing configuration or anything. So I tried to upgrade to the latest version but it is still the same. Would be great to discover bug or cause of this problem. I cannot imagine I would control whole house and this happen. I have my configuration saved but, reinstalling or just discovering what’s going on is not good for production use.

Guys after lot of trials and errors I got UI finally working, I removed pip .cache folder in /home/hass folder (installed with all in one installer on raspberry pi ) I am still getting error at component recorder but UI is working .

Ok. Thank you. When I come back, I will try.

maybe this thread can help someone with same or similiar problem
