Domain name not updated under Linux

[GGC]

Hi all

My Domain name is not updated (ie the dynamic IP address linked to the domain name does not change when the IP address changes) when subsonic is running under Linux Mint 18.3. This happens also without firewall.

Same version of Subsonic works properly under Win 10.

Any suggestions? Thanks.

License Subsonic Premium (expires May 29, 2018)
Version 6.1.3 (build e408c9) – October 31, 2017
Server jetty-6.1.x, java 1.8.0_151, HSQLDB, Linux (78.7 MB / 133.0 MB)

[toolman]

And what does the logfile tell you?
Did you check under Settings > Network what status is indicated?
Did you rely on Subsonic to set the portforwarding or did you do it manually?
Does your Server have a static ip-adress in your LAN?
Did you check the settings in your router?
