Hello.

If so, first you need to migrate EC2 to IPv6.
Specific steps are described in the document below.
https://docs.aws.amazon.com/vpc/latest/userguide/vpc-migrate-ipv6.html
Also, please note that step 4 of the above procedure may differ depending on the EC2 OS.
By the way, if the ISP you are using does not support IPv6, you will not be able to connect to EC2, so please check whether your ISP supports IPv6.
