[2023] Any fix for the Halo Waypoint login errors? Tried multiple browsers and devices but cannot get in to claim my drops.

couple more thoughts:

try xbox.com first and then halowaypoint (try after a fresh cookie/cache clear for maximum effect)

try a different internet source like your phone's hotspot.

i would honestly try seeing if you can use a different internet source (friend's wifi or something)

it's not always but that error can be some weird ISP thing sometimes
