Cant load Keys in Sparkfun RTK

Using Verison 4.0 connects to wireless but says Keys not listed, and ZTP error.

Welcome Simpsriu!

What RTK device are you using?

Can you provide us with your device ID? I will double check that it is properly whitelisted.

Based on our event logs, I think we found your device and whitelisted it. Please try obtaining keys again.

that worked thank you. I have another unit that will not power up. Any thing I should be looking for???
