@Family_AM Hey

1. I guess you set up DDNS because you use features such as port forwarding or remote access, right ? You can try to use this function with the domain name as well as the IP separately to verify that you can use these functions properly. If you can use the function normally, that means the problem is that the IP of the DDNS interface is not updated and has nothing to do with the controller.

2. You can also consider deleting your current DDNS settings and reconfigure the settings.

@Yannie thanks for detailed answer and suggestions.

Yes, I have a NAS server and I have some FTP that use from remote backup. I have configured the same account and DDNS on my NAS that has DDNS update feature and it works fine.

I tried deleting it, adding even using a different account and domain and is not updating. Also nothing on event logs that can guide what is wrong.

I believe is an issue of the Omada SDN. 

@Family_AM 

That's strange. What's your previous version of your controller ? Have you changed any network settings since the upgrade?

@Yannie no, no network changes or so, I upgraded from v5.0.15 to v.5.0.30,.reading some other post on this forum there other 2 people complaining on same issue with v.5.0.30 I wonder if anyone use this function and is working to discard is something with my setup or and Omada issue.

Thanks again for your reply

@Family_AM I don't have good advice anymore, maybe you can email their tech support and have them do a deep troubleshooting
