Help? I reset my hardware controller and retored from a recent backup. The ddns address changed and none of my devices reconnected. I tried going to the web interface of the devices, but they are all blank like the picture. Is tehre a way to get my devices pointed to the restored controller without factory resetting them? I can still SSH into my devices. Is there a way to update the URL that way? ![Screenshot 2024-09-01 at 08.37.16](https://forum.alta.inc/uploads/default/original/2X/3/370c16c59a2b50b9c1aad4fff8ea2089c0680127.png) ---

I’m not sure on the location of the URL but you can reset them over SSH Edit: I lie take a look under /cfg/domain.txt ---

@Alta-Jeff can you help me with this one? Currently, how could I add a switch back to the hardware controller after it has been reset and restored from backup? The DDNS address changes and the devices say offline. ---

@anon77415413 If you are able to ssh to the device, you can do this: /etc/init.d/rc stop echo [local.12345678.ddns.manage.alta.inc](http://local.12345678.ddns.manage.alta.inc) \> /cfg/domain.txt rm /cfg/rcapi.txt /etc/init.d/rc start And then you should be able to click Set Up again to preserve the switch’s config. If you don’t have ssh, unfortunately you’ll need to physically reset the unit so that you can access the web site on it to set the updated controller URL. Hopefully this helps! -Jeff ---
