Apple ID sign-in is not working from Linux OS browser (Chrome, Firefox...tried both with new session cookies cleared, and incognito). I can browse apple.com without issues. I needed to check Apple ID after getting what appears to be a bogus security alert on my iPhone about a FaceTime sign-in on my table.
I've tried to login to Apple ID page from 3 different public IP addresses (cities) and Linux based desktop & laptop computers with latest updates. Login works fine from a Windows computer.
I spoke with Apple Support and they said:
we are only trained on Apple products so we are unable to help you with that.
When they said they could escalate it to one of the engineering teams and get back to me, I offered to give the Chrome and Firefox versions along with the OS information and again I was told:
we are only trained on Apple products. That information will not likely be useful to our team.
I can't imagine telling one of my customers that when questioned about a cross-platform compatible product/service I provide. It's specifically a bad gateway reported by Apple server and only happens when trying to connect from a Linux computer.
This has never been a problem for me in the past. I figure since the error is reported directly from Apple servers, they made a change in their firewall. I'm not sure what else to try with Apple Support. How do you resolve this?
