Yeah, but I don't get browser popup. This screen appeared after latest firmware update, can't remember was it a browser popup previously. So either you don't use latest version or explain to me what is going on 🙂
Like I said, I tried with browsers I never use. I am web app architect, I know all of this stuff.
Correct. My system is an old RBR50, not an RBR350.
Since this is not a browser popup, then it should be possible to view the page source code, and a Wireshark capture would verify that it is not the typical HTTP GET - HTTP 401 pattern.
