I have a problem with using dds in aws ec2 (ubuntu). I can run my code of dds program in my raspberry pi 4(s) in LAN, but when uploading the code on two ec2 which are in same subnet (and VPC) and whose security group allow all traffic to each other, they cannot find each other by discovery.
By the way, I have tested mqtt on node-red, two ec2 can transfer message to each other using private ip (same subnet).
Do anyone can give me some suggestions for this situation?
Thank you!!!
