Dynamic DNS IP address changes and Com'X 510 stops publishing .csv files

[swil]

A Com'X is uploading .csv files to a server, but each time the dynamic DNS IP address changes, it stops publishing.

On the Settings/Publication page the dynamic DNS address is entered in place of a public IP address.

Can anything be done to force the Com'X to keep track of the public IP address when it changes periodically?

About page for Com'X 500 shows:

Application Version 5.2.0

MCU Board FW version 2.2.6

Root Partition version 4.2.2

Soft Partition Version 5.2.0

Hardware Version 5

We've investigated previously and found we were unable to get the Com'X to update the IP Address.  ("adding the JVM parameters to not cache the DNS entry did nothing...")
