Gateway already exists

Hi, I recently delete my gateway with id 782184FFFF9990C8 because a problem with it, but now I want to register again this gateway, perhaps ttn say that’s already exists. What can I do?

If is been deleted try to re-register using same EUI but selecting a new Gateway ID - free form text of your choice/convenience…just dont pick something obvious that another user may have chosen…‘myttngw’ may have been used… menysttngwno1001 likely not!
