I am trying to activate the ID app on my firestick. I enter the code and then select Cox as my provider then the next screen gives me ...” forbidden and a code. I can’t get past this screen to finish activation.
Not Fire related, but I had that problem with Roku. I wanted to stream a mini series from PBS and I got the forbidden messages. PBS hated all the privacy settings on my browser: Private Browsing, Tracking Protection, Do Not Track add-on, No Cookies ever, etc. I temporarily disabled my settings, entered a new verification code and it worked.
It was kinda dumb because I just re-enabled my settings.
FYI, when I got the 500 error message it was in Chrome "incognito" tab with no add ons or anything. I really do think it's related to simular errors other people were reporting when trying to sign into webmail. I even tried through a proxy, and got the same error. I should note I don't have Cox TV service, but was able to sign in with my Verizon login just fine, so pretty sure it's a Cox issue.
