Failure to add devices to chirpstack server

Can anyone find out why I am having trouble adding the device onto chirpstack network server?
Operating on the assumption that the details i have filled up below is correct.
Also do reply if you don’t find anything wrong or if you find anything weird or out of the ordinary


it just started working. nevermind.

Glad you sorted it, just in case for future reference is the device profile available handy?
Could you share them for reference.

there is not a lot of things i did afterwards to make it work. it just started working and I have no idea why. I keyed in the details several hours ago and after i finished typing the question, it just started joining.
I only added DevEUI, and AppKey, JoinEUI is available via OTAA
