Did some more testing to try and provide a bit more info.
* The config is default. Firmware reset and updated to latest version (v1.1.1), then connected to my Wifi, tried a few different settings by picking USB-tethering etc, but it makes no difference.
* Connecting through the Management AP makes no difference
* Browser is Chrome Version 93.0.4577.63 (Official Build) (64-bit)
* OS Ubuntu 21.04 if that helps
* Another screenshot of the console in Chrome (basically the same info though, but this really keeps spamming constantly on the recon page)
* Using Firefox instead makes it worse. It doesn't even ask me for a password it just gives me an empty page, probably a view/template with no data.
