Cannot add device "duplicate sysName"

I am trying to add a device that due to a firewall rule I could not ping. After I fixed the firewall issue and can ping the device I get this error message:

However, I cannot see it:

The 10.0.31.2 is the one with Mikrotik sysName.

If you want to allow duplicate sysNames, set this in your config.php:

$config['allow_duplicate_sysName'] = true;

But I strongly suggest you to change the sysName in the new (or the already monitored) Mikrotik router to something else, like you have in the others.

Thanks, I did not catch that detail.
