Cheap 2nd hand android tablet unable to load HA through Chrome and Kiosk but the HA app is fine

Recently brought a cheap android tablet for a simple desk mount for HA control. App works fine on it but access from a web browser hits me with the below errors

dns_probe_finished_bad_config
and
dns_probe_finished_nxdomain

Have flushed DNS, gone static, tried both standard local url and IP. Ran through suggested troubleshooting online including the below.

No other issues with any other (admittedly all apple) devices, no issue with the app on the new device, its just throwing up errors when I try to get in from both chrome and fully kiosk browsers. Having the app but not the web ui work is bugging me way, way more than I should admit.

Open to any and all suggestions…and I do mean any.
