After our full sandbox was upgraded to Winter '22 our Mulesoft Anypoint connected app is getting a OAuth Error - "We can't authorize you because of an OAuth error. For more information, contact your Salesforce administrator. OAUTH_APPROVAL_ERROR_GENERIC: An unexpected error has occurred during authentication. Please try again. "
This connection was working prior to the Winter '22 upgrade.
The connected app has access to ALL scopes.
Anyone else having an issue in Winter '22 ?
Here was the answer:
The Salesforce Technology team became aware of the service disruption impacting your sandbox instance. During the service disruption, customers can’t login to Salesforce and access any of their services. Upon investigating, the Technology team noted a recent Winter '22 Preview Release on Patch 3.6 version as the potential cause of the incident and decided to roll back to Winter’ 22 Patch 3.2.
