Hello,
Thank you for letting know about Your issue.
I will introduce few points:
1. If you had newly added device without any firmware update or action performed the item history should be blank.
2 If you added a CFG file you need to double click on last update and you should see Date, File name and Status. You can filter the date and you should be able to see the last device configuration has been added.
3. If you added a new firmware version you should see it which firmware version you just downloaded and when last update was made. If you double click on last update you should see those parameters Data, File name, Status. You can filter the date and you should be able to see the last device firmware has been added.
In order to confirm that FOTA program is working correctly and that's it not a software issue we would more detailed information, would you mind sending us a screenshot of your issue in FOTA software window.
Did you tried to reinstall FOTA? maybe some files can be missing or corrupted from older version.
If Your hardware key was changed you have to inform Your responsible sales manager he will provide You with a new licence key.
Best regards.
