The ping between two CVM instances in the same VPC fails.
If an ACL is bound and ICMP is rejected in the ACL, or there is no ICMP rule in the ACL, then click the ACL ID to enter the ACL page, allow the corresponding protocol and source/destination IPs, and move the rule to the first place so that it will be matched first. Then, ping again to see whether the problem is solved, and if not, proceed to the next step.
If no ACL is bound, or the ACL rule already allows the corresponding protocol and IPs, proceed to the next step.
