Hello,
Could you try updating to the newest version to see if that resolves the issue? If the newest version (14.2.9) isn't available for the auto-update you can download the software from the Customer Service Center. In order to access the download link to the newest version please log into your online account and download it there. Please use the email address the license is registered to and your password to log in here:
https://service.paessler.com/en/login/
Once you have downloaded the newest version there, you can install it directly over the version currently running. The configuration and database will not be affected by installing the newer version over the old and the configuration is automatically backed up before this process.
Should the issue then persist, please send us a screenshot showing the AD-Settings that you want to enter. Please send the screenshot via email to [email protected] with a reference to this KB-Thread.
best regards
