core: (new) reolink NVR shows error

The problem

Using today’s Reolink integration from https://github.com/home-assistant/core/pull/84081 on <dev> code, with admin/password and dns-name for the NVR, it seems to basically work, except I saw the below error. Otherwise my NVR seems to be working OK, and IIRC the HACS version (different install of HA here) was working OK too.

I’m not using any proxy etc, and in fact the NVR is connected (wired) to the same switch as my dev machine, which is running this code.
