Plex Server shows as Offline on Android and iPadOS App - 401 error

@ChuckPa and team,

Same issue like in this post:

Can access via Web without any issues, but media does not show up while using App on Android or Apple iPad. Get 401 error when trying to access media settings in the dashboard.

Please check certificate.

Thanks.
