Already installed filemaker server 15 in AWS EC2.
The FM SERVER IP Addresser shows 172.
Just try to upload to the numbers before the comma. e.g. 172.xx.xx.xx
The 172.xx.xx.xx number is ipv4 address
The 2001:0:.... is the ipv6 address.
You could also use just the ipv6 address (after the comma) but that choice is yours.
That address does not look correct; EC2 gives you a public DNS name, use that one.
In addition to using the correct address, make sure you have the correct ports open on both the Windows OS Firewall, and the AWS Security group assigned to the instance. I would recommend sticking with the IP4 address, to keep things simple, but if you use the ip6 address, make sure you Security Group also has CIDR rules for ip6 as well.
Thanks a lot! It works with AWS EC2 Public DNS(IPv4).
Also note that your IP address will be dynamic unless you attach an Elastic IP address to your instance, unless you are using FileMaker cloud that is.
