In case someone is interested, the problem was with the webserver not starting up. From the serial I accessed the shell and found the webserver not running, due to an incorrect path for the ssl cert in the config. Don’t know if this is due to the upgrade/restore profile process, or if someone messed with the config before I took over this device (probably the latter).
After rectifying this and starting the web server, I was able to access with browser, and all the config was in place correctly.
