    I’ve just applied patch 4 as per the release notes and can no longer send email from the modern client (nor the classic app), even after starting the server (RHEL 7.8).

    The Modern interface continually throws a GraphQL error: “GraphQL error: Unexpected token < in JSON at position 0" and mail cannot be sent.

    Has anyone else seen this or knows how to fix? This is a major issue at present.
