Why doesn't ping reach servers behind the ASA in Cisco Packet Tracer?

Question

Cisco

Good afternoon! I'm starting to study cisco built a small scheme, it seems to have set everything up, but there was a problem: the end PCs cannot reach the servers behind the ASA, I can't understand why, the routes seem to be nat also configured. I ask the help more skilled in Cisco. Thank you in advance! File with Cisco Packet Tracer attached.
