How do I set up communication between Digital Ocean VMs? I created two VMs, but they can’t communicate with each other!

Heya,
How are you trying to make them communicate between themselves?
Make sure the VMs themselves don’t have restrictive iptables or ufw rules blocking the traffic and also if you are trying to reach them through SSH make sure to allow them on the said ports and so on. If you give more info, I can further help you out.
Heya, @securityangler
What is your end goal here, or more like what is your exact requirement when it comes to communication?
You can use VPC. In this way, your droplets can talk to each other over private IPs without exposing that traffic to the public internet.
If you created both droplets in the same project/region, they’ll already share a VPC private network. You can confirm in the DO control panel under Networking → VPC. Each droplet should have a Private IP in addition to the public IP.
