Home assistant local not working

Hi there guys. I have been running Home Assistant for a while now without any issues at all. I could connect both locally and via nabu casa, without any issues. However, this morning I updated HA core and thereafter I can access my HA via nabu casa but not locally. My brain feel fried, cannot think what the problem can be. Any advice will be highly appreciated. Thank you in advance.

You can not connect to <ip>:8123 with either http:// or https:// in front of it?

Are you sure that HA have the IP address you think ? Check the IP information in the network setinng page in HA.

Check the output on the monitor on the HA server/VM also.

Are you using the MDNS address (homeassistant.local) or the IP address?
