Connection to Vault (Vault Status error) ( ...dial tcp 127.0.0.1:8200: connect: connection refused )

[Joey S]

This issue occurred when we tried to implement https. We are rolling back after some problems but now http connection to the vault doesn't work. We looked online to find several solutions that doesn't quite apply to us. So we are having issues with a vault instance that was working but doesn't seem to be listening anymore.

The vault status responds with the following

Error checking seal status: Get http://127.0.0.1:8200/v1/sys/seal-status: dial tcp 127.0.0.1:8200: connect: connection refused

our config.hcl has this for the listener

listener "tcp" {
address = "127.0.0.1:8200"
tls_disable = 1
}

After modifying the vault we make sure to stop and start the vault service.

env | grep VAULT returns the following value
VAULT_ADDR=http://127.0.0.1:8200

I looked around online and these two links seem to have similar issues

The tips mentioned in the links above didn't seem to help. I'm wondering if this is an issue with changing a configuration file on a running vault.

Let me know if you need more information.

Hi Joey,

There's no problem with modifying the config while Vault is running, it only reads the config on startup (and, for a subset of configuration, upon receiving a SIGHUP.)  I don't know why you're getting connection refused but the most likely explanation is that Vault failed to come up.  What do the logs say?
