-RESOLVED-
u/juzmafia suggested I turn off IPv6 in network settings and I was able to sign in.

I am getting Error Code 42 from Disney+ on both my Sony A80J and my Shield Pro.
I have reset my network, unplugged all devices, uninstalled and reinstalled Disney+.
Disney support is telling me it’s a known issue but I can’t find anyone else having this problem online.
Am I alone or has anyone resolved this?
Thanks in advance!
On Shield TV, have you disable IPv6 under network settings?
Might not related to your issue but currently there's playback issue with some Atmos content on Disney+ after the SE 9.0 update.
