Trouble after reboot

I have the most current volumio installed on a pi 4 4 gig, 64 gig samsung evo sd, and music is on a 256g samsung thumb drive.

I have had it working several times, but if I shut down the pi for any reason, I cannot connect to it, either by volumio.local, or by IP address. I have been using an ip scanner to get the pi ip. I can ping the ip, but cannot connect to the pi. It says refused to connect.

I have tried reflashing the sd card(etcher) then adding ssh to the boot, and same thing, first boot, I can connect, but if I shut it down, I cannot connect again.

What am I missing?

Thanks
