Surface: Authentication API · application/problem+json Type URI: https://docs.zeroset.com/problems/invalid_qualification_issuer Code: invalid_qualification_issuer HTTP status: 401

Resolving it

Ask the deployment operator to verify the configured issuer trust and request signature. This is not an end-user authentication failure; refreshing a user session will not resolve it.
