Hi all,
I erased some contacts I used for testing my campaigns, and then recreate them in order to start from scratch. I thought Mautic would start tracking from scratch also but now Mautic don’t want to track visits coming from these contacts using the same IP. I understand it considers it could be another person using the same IP.
It doesn’t match the contact and the IP anymore so there is no tracking website visits anymore for these IP.
I promise I won’t do it again, but for now, does anyone know how to fix it ?
Thanks !

@contal what about the IP location file have you store on your mautic root?
