Been plugging away at this issue, but found out the issue was actually with my router setting behind the brume 2... For whatever reason my router changed where its DNS was coming from. I suspect during the firmware/reboot it went around the adguard and found a site for DNS. I moved my router DNS back to "internet" which is the brume in my case and things are now back to normal.
I had contacted support and their diagnosis step was to plug a computer direction into my brume and see if anything was blocked. WHich is was. THat pushed the issue back up stream to my router.... Hope your issue similar.
