Timeline of updates

  1. update

    A recent security update for Common Runtime applications in the EU region may have unintentionally enforced a stricter policy for TLS certificates used for app default domain TLS termination (<app>.herokuapp.com). This caused some clients to experience TLS handshake failures and to be unable to connect to apps.  Engineers have identified the issue and we are working on remediating.

  2. update

    Engineers have remediated the issue.
