Wifi Mesh Extender (EX6400) Not Working & Multiple Colored Lights On

Hi.  Trying to get help on a wifi extender that was working and no issues until recent.  Noticed my extender has multiple colored lights on and will not connect to my Netgear Nighthawk app.  To me the unit seems to not be working.  The router and client links are solid amber, arrows are solid blue and power is solid amber and WPS is solid green.  They have always been all solid green and usually have been able to access my app and details.
