Question
I think I'm missing a step. I cloned the repo, set the vars, ran terraform init, terraform plan and then terraform apply.

I got Apply complete! Resources: 41 added, 0 changed, 0 destroyed..

Then, I ran the root_token_decrypt_command and got the token. Set VAULT_ADDR, VAULT_TOKEN & VAULT_CAPATH as pert he README.md.

Assuming this is all correct, I should be able to interact with vault. Except I get...

Error enabling: Post "https://<IP>/v1/sys/mounts/secret": dial tcp <IP>:443: connect: connection refused

Upon digging a little further, the load balancer is reporting that the health check is failing for all 3 instances.

Considerations
Is there a step I'm missing? Any pointers on what I can look into next?
