Hello @Pentagon2442, welcome to the community and to OpenZiti! That is a **very** interesting issue you have there! I would not expect a 400 to come back from the enrollment. Can you detail the exact steps you've followed so that I can try to reproduce what you're seeing? I have very recently done exactly this setup, but used docker instead of CentOS 7 VMs. Maybe that thread would help you?

Now I have created them with OpenSSL, maybe should I have used they built in Ziti commands It's certainly easier if you let the quicsktart generate the PKI for you. It's a **very** delicate thing and exceptionally easy to get wrong. We recently added this to try to explain what a quickstart does and how the PKI is structured etc [Quickstart Walkthrough | OpenZiti](https://openziti.io/docs/learn/quickstarts/network/help/quickstart-walkthrough). Maybe that will help too. I'll be happy to help you get your setup rocking. Take a look at those links first, show me the exact sets of commands you've run and I'm sure we'll get you rocking in no time. --- _[View the full topic](https://openziti.discourse.group/t/building-simple-network-from-scratch-help/2098)._
