Need help accessing HA front end

Ok, so i’ve had hass.io up and running for months. I leave for a few weeks and return and no longer have access to the front end. I’ve tried different browsers, wired, wifi, etc, but cannot get to the front end. I have access to the command prompt but do not know where to start to assess what’s going on. Any suggestions on how to regain front-end access?

From the command prompt:

hassio homeassistant logs

To see what is going on.
