License Transfer to a newly built Server

I recently “rebuilt” an old server…switched from Windows Server 2016 to Ubuntu Server 24.04.4 LTS. Same hardware. Same drives (reformatted from NTFS to ext4). Same server name. And I would like to transfer the existing license to the newly built machine, but I keep getting the following error no matter how many times I change the hostname on the License page.

“Failed to download the license: License error: Activation code has already been assigned to a different host and can’t be activated on xxxxxxxxxxxx. Please log in to your Duplicacy customer page to change the hostname associated with the license.”

What am I doing wrong? many thanks in advance.

Go to your account and change hostname associated with the license, and then activate duplicacy instance again. I assume the activation code will change

I changed the host name four times and reactivated four times. Same error all four times. Do I need to wait a certain period of time after changing the host name before reactivating?

Hmm I’m not sure what’s up, but afaik there shall be no waiting period. I don’t have access to licensing. @gchen?
