NoHostAvailableException in DBeaver when connecting to remote Cassandra docker container - docker

Question

I have a Cassandra instance running in a Docker container on an Intel NUC. From my mac, I can ssh onto this and connect to the cqlsh fine. However, when I try to connect using DBeaver Enterprise I get:
com.datastax.driver.core.exceptions.NoHostAvailableException:
All host(s) tried for query failed (tried: myhostname/xx.xx.xx.xx:9042
(com.datastax.driver.core.exceptions.TransportException:
[myhostname/xx.xx.xx.xx] Cannot connect))
This occurs with and without SSL enabled. I also have an SSH tunnel enabled successfully configured, but I have also tried with this disabled.
On my NUC, I appear to have three ethernet interfaces; the usual enp0s25 and also docker0 and br-65e6f96b0e4f. I have tried the associated IP addresses with these two interfaces which seem to appear to be doing more, as they pause a few seconds, but ultimately throw the same exception.
Versions:
Cassandra - 2.2.8
CQLSH - 5.0.1
DBeaver Enterprise - 3.7.8
Looking in the debug log I see the following messages (SSH tunnel enabled with public key auth):
