Gateway not accessible

I was trying to migrate the gateway from v2 to v3 server.
I created a gateway on the v3 server but during the process something got deleted and I can no longer see the gateway but cannot re-add it because it is in the database and complains that the EUI already exists(C0EE40FFFF2942F4).
Is there a way to delete that instance of the gateway so that I can start again??

Hi, it looks like instead of deleting the gateway, you just deleted your rights on the gateway. I’ve restored the rights.
