Tommy Stendahl commented on CASSANDRA-14842:
--------------------------------------------

I this config on the 4.0 node:
{noformat}
server_encryption_options:
     # set to true for allowing secure incoming connections
     enabled: true
     # If enabled and optional are both set to true, encrypted and unencrypted 
connections are handled on the storage_port
     optional: false
     # if enabled, will open up an encrypted listening socket on 
ssl_storage_port. Should be used
     # during upgrade to 4.0; otherwise, set to false.
     enable_legacy_ssl_storage_port: true
     # on outbound connections, determine which type of peers to securely 
connect to. 'enabled' must be set to true.
     internode_encryption: all
     keystore: /usr/share/cassandra/.ssl/cil-intern/server/keystore.jks
     keystore_password: '*********'
     truststore: /usr/share/cassandra/.ssl/cil-intern/server/truststore.jks
     truststore_password: '**********'

> "enable_legacy_ssl_storage_port" set to true so it should accept incoming 
> connections on the "ssl_storage_port".
> I have also tried to upgrade from 3.11.3 to 4.0 and this was also 
> unsuccessful. the 4.0 node does not establish any connection to the old nodes 
> but I can't find any errors in the logs.
