My core is on a ausu mini computer pn51 （amd5500u），music files are in qnap nas，control by买notebook，they all link via 2.5g network switch，Internet connection through gigabit optical broadband。
My core is usually 24-hour power on。But，why are the covers and avatars of albums and artists in my software black every time I open the software in my notebook?It often takes a long time to refresh the album cover。
Where are the caches of these album covers and art season portraits stored？
what remote are you experiencing this on?
does your pn51 have an SSD?
Try this: Clear image cache from : settings - setup - clear image cache
yes，harddisk is ssd
yes I tried。But it doesn’t work。I tried even the thumbnail that just refreshed. After I switched several settings interfaces and returned to the album interface, the cover was gone again
