Invalid or Expired License - Sudden Error Message

Hi, I’ve been using the web-ui for a while now, and I applied a paid license to it a couple of months ago.

Suddenly my scheduled backups are failing with the error “Invalid or Expired License”.

However, when I click the “Personal” link in the backup section to check my license it confirms I have a valid license: 21
“This computer is running with a personal license that will expire on 2021-01-19”

I searched for this in the forums and found a macos terminal command to run, but that doesn’t work either:
defaults delete com.acrosync.mac.duplicacy License
2019-03-22 07:17:46.800 defaults[4355:1776078]
Domain (com.acrosync.mac.duplicacy) not found.
Defaults have not been changed.

What can I do to fix this?

The saga continues. I quit and restarted the app, now it’s telling me “This computer is running with a trial license that has already expired.”

When I try to apply my license key from the customer portal, it gives me the error message “Failed to download the license: License error: Activation code has already been assigned to host localhost. Please log in to your Duplicacy customer page to change the host”

What do I do?

Go to Log in required and click on the link that says localhost under the Host column. Then you can change it to the host name of your computer.

Hmmm, the problem came back for me when I upgraded to the WebUI v1.

I verified that my hostname matches what’s in the customer portal, but Duplicacy still says trial. When I try to paste in the key, it says it’s already being used by my hostname.

Just to make sure I’m not out in left field, I check my hostname (MacOS) by going to:
System Preferences > Sharing


The host name seen by Duplicacy is different from that on your customer page.

I’ll message you the correct one.
