RBR750 403 Access denied after upgrade to 4.6.3.7 firmware
I'm getting a proxy error from the router, and am unable to access its configuration page after firmware update from 3.x version to 4.6.3.7.
I factory reset the router, and then I'm able to connect again; however, when I re-configure it (restore settings), the proxy error comes back.

Access denied
The administrator of this proxy has not configured it to service requests from your host.
Generated by tinyproxy version 1.11.0-rc1.

I've tracked it down to the following:
I configure my router to be 192.169.0.1, rather than the default 192.168.1.1, and this configuration has worked well before (using 3.x firmware) and is necessary due to the topology of my various networks.
Anyhow, the new firmware is unable to handle this setting, even though the 3.x firmware worked fine.
Furthermore, the web application is not allowing me to downgrade to the older firmware because the "Yes" button that is required to answer the "are you sure you want to install older firmware" is missing from the UI.
Any hints on how to get around this error or an easy way to get past the "missing Yes button" part of manually downgrading.

What browser are you using?
Bye restoring the configuration, are you manually inputting settings or restoring from a backup file?
If you disconnect the RBR from the ISP modem, can you log into the RBRs web page and select the ERASE function from Advanced tab/Admin/Backup using a wired PC and web browser? Try MS Edge or Firefox or Opera. After the RBR resets, log into the RBRs web page at 192.168.1.1 and walk thru the setup wizard...
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
I tried Brave, Chrome, and Edge browsers, all with the same effect.
I've isolated the change to what I stated: i.e. I can make the error happen simply by taking the initial default configuration (after walk-through setup) and trying to change the router ip address to 192.169.x.x rather than 192.168.1.1.
The issue happens regardless of whether or not the router is connected to the cable modem.
Modem is Netgear CM1000.
You'll need to keep 192.168.1.1 for now if this doesn't cause a problem.
I recommend you contact NG support and let them know what your seeing when you try changing the IP address from .1.1 to something different.
- easy way to get past the "missing Yes button" part of manually downgrading.
In another thread it's been suggested that the "Yes" button can be found by examining the page HTML. Haven't tried it myself.
