No spectrum pick up- New User

Hi I’ma new user and Kraken out of the box. I got it set up but when I check DOA out spectrum on web server I get a null spectrum just all waterfall orange even when I put a weak beacon in a field nearby at 915 to see. DAQ says everything working fine.

Could you please take a picture of the Kraken connected to the antenna array?

I got it figured out. I think there was an issue with my original pi 4 changed it out and worked fine. Thanks
