Is Dynatrace Managed able to run without the Cassandra and Elasticsearch services?

I am adding a new node to the Managed Cluster, but at one point it says the joining failed because couldn't talk to port 7000, 9042, 9200 an 9300 of the existing Managed.

So it seems like a port issue, but the thing is the two server are in the same subnet, so there is no firewall rules between them. The only possibility left seems to be the services (i.e Cassandra-based Hypercube storage and Elasticsearch-based search engine), which also seems to highly not possible.

What could've gone wrong?

This connection must be established, maybe those ports are blocked and not exposed on os level, only idea I have.

To answer your original question: Dynatrace Managed node cannot run without Cassandra and ElasticSearch. They are required components.

I agree with Sebastian, this sounds like a firewall.
