Problem registering Dragino ldds75

I am having trouble registering a dragino ldds75 node to a rak7249 gateway. I deleted my first attempt at creating and application/device, and my second attempt is not registering with credentials from the devices sticker.
Have I locked myself out by deleting my first application - which I am sure did not register correctly either? Thanks

I’ve moved this to the End Devices - Dragino category.

You don’t register to a gateway, but to make sure we understand things, are you registering the device on TTN?

And if so, yes, deleting isn’t a good move, it’s better to edit.

What error messages come up when you say “not registering” on your second attempt?

yes TTN, but all good, I didn’t set my gateway up correctly. Problem sorted. Thanks
