DSE LifeCycle Manager can't upgrade to newest version

I can't perform an upgrade to the latest version of DSE via Lifecycle Manager. Specifically, it's that I can't point to a version higher than 6.8.43 (that's also the current version used on nodes). Both on the server with OpsCenter and on all hosts to be upgraded there are DSE packages version 6.8.47 available in the repo. yum search all dse --showduplicate | grep "6.8.47" dse-6.8.47-1.noarch : This package contains the full dse distribution. dse-demos-6.8.47-1.noarch : This package contains the dse demo applications. dse-full-6.8.47-1.noarch : This package contains the full dse distribution. dse-libgraph-6.8.47-1.noarch : This package contains the dse graph libraries. dse-libspark-6.8.47-1.noarch : This package contains the dse spark libraries. dse-libcassandra-6.8.47-1.noarch : This package contains the dse cassandra libraries. dse-libhadoop2-client-6.8.47-1.noarch : This package contains the dse hadoop 2 (client) libraries. dse-liblog4j-6.8.47-1.noarch : This package contains the dse log4j libraries. dse-libsolr-6.8.47-1.noarch : This package contains the dse solr libraries. dse-libtomcat-6.8.47-1.noarch : This package contains the dse tomcat libraries. Until recently, it worked seamlessly. Now it's like this: What is the problem?
