Don't see an error here. Can you check logs in /var/log/ranger/kms/?

[#3]

Error is:

2015-10-01 21:01:17,660 - Error : [Errno 110] Connection timed out

[#4 · Accepted solution]

You showed this error:

Error : [Errno 110] Connection timed out

That means the Ranger KMS services cannot reach the Ranger Admin service (http://rangeradminhost:6080).

Verify that "External URL" is set properly for Ranger & Ranger KMS. Typically it's `http://hostnameofrangeradmin:6080`

Common mistakes I've seen:

• Putting a `/` on the end. It won't work with this.
• Using a hostname which is not resolvable internally between all of the hosts. (The name "External URL" is confusing since it's really the "Internal URL")
  • Such as setting to `http://localhost:6080` which will only work from the Ranger Admin host

The KMS is also backed by a DB. Make sure kms db user/host combination has been granted permissions in MySQL (if that's what you're using).
