Spark. The history is not loaded from the Openfire server

Good afternoon. I installed the Openfire server with the Monitoring Service plugin. I’ve set everything up. However, the Spark 3.0.1 client does not load the message history from the server.
everything is loaded in the Gajim client. What could be the problem?

Spark, sadly, does not yet support the MAM protocol that is providing this functionality. This feature requests is captured in this ticket: [SPARK-1728] - Ignite Realtime Jira
