Ipad and apple pencil issue

While my apple pencil was charging, I plugged in ipad charger.. after like 30 min later when I came to use my ipad, I noticed that my apple pencil is not connecting with my ipad anymore ! I've tried restarting, tried resetting, but my pencil is not working anymore. When I attach with with the charging area of the ipad, it shows apple pencil logo on the screen for some time.. but doesn't work.. what should I do now!!
