Descriptions

For MongoDB Ops Manager versions prior to and including 4.2.24 with multiple OM application servers, that have SSL turned on for their MongoDB processes, the upgrade to MongoDB Ops Manager versions prior to and including 4.4.12 triggers a bug where Automation thinks SSL is being turned off, and can disable SSL temporarily for members of the cluster. This issue is temporary and eventually corrects itself after MongoDB Ops Manager instances have finished upgrading to MongoDB Ops Manager 4.4. In addition, customers must be running with clientCertificateMode=OPTIONAL / allowConnectionsWithoutCertificates=true to be impacted*.* Customers upgrading from Ops Manager 4.2.X to 4.2.24 and finally to Ops Manager 4.4.13+ are unaffected by this issue.

Para MongoDB Ops Manager anteriores o iguales a la versión 4.2.24 con varios servidores de aplicaciones OM, que tienen SSL activado para sus procesos MongoDB, la actualización a MongoDB Ops Manager anteriores o iguales a la versión 4.4.12 desencadena un error en el que Automation piensa que SSL está desactivado, y puede desactivar SSL temporalmente para los miembros del clúster. Este problema es temporal y finalmente se corrige por sí mismo después de que las instancias de MongoDB Ops Manager hayan terminado de actualizarse a MongoDB Ops Manager versión 4.4. Además, los clientes deben estar ejecutando con clientCertificateMode=OPTIONAL / allowConnectionsWithoutCertificates=true para verse afectados*.* Los clientes que actualizan de Ops Manager versión 4.2.X a la versión 4.2.24 y finalmente a Ops Manager versión 4.4.13+ no se ven afectados por este problema
