502 bad gateway

When I login my Adobe account,

input email address > verification code > password.

Adobe is required me to change password.

Click “Continue” to change password.

but I don’t know why there is no any response and Adobe return 502 Bad Gateway even if using my personal device(no vpn), and it should under different network settings.

We have more and more of our dept colleagues were need to change password but return 502 bad gateway, cannot login Adobe
