The VScode Remote extension is not supported on the DCC Clusters. Several users are using it anyway.
If you are one of those users, and after a recent update you encounter the error
The remote host may not meet VS Code Server's prerequisites for glibc and libstdc++
it means that the version you installed is not compatible any longer with the OS running on the Cluster.
The solution is to downgrade to the last version compatible, version 1.85.
