Can't connect to iphone hotspot

I recently bought a Dell Latitude 12-7275.  I also have a new IPhone 8.  When I try to connect the Dell to a hotspot through the IPhone, my Iphone flashes several times at the top and bottom of the screen, and then the Dell gives me a message that it "Can't connect to this network." 

I'm running Windows 10.  The Iphone data is through Verizon.  I have installed all Windows updates.  I updated all of my drivers through Dell, and then I updated my wireless adaptor through Intel.  The wireless adaptor is a Intel Dual Band Wireless-AC 8260, and I have installed Driver 20.0.2.3. 

Please help!

Thanks.
