## Problem

Confluence with SSL doesn’t work properly due to the domain from SSL Certificate doesn’t match with the requesting name.

The following appears in the atlassian-confluence.log.

2015-03-04 10:09:07,312 ERROR [http-8190-2] [renderer.internal.http.HttpClientFetcher] fetch Unable to retrieve response

javax.net.ssl.SSLException: hostname in certificate didn't match: <jira.test.com> != <confluence.test1.com> OR <test2.com> OR <confluence.test3.com>

## Diagnosis

The steps below can help to confirm the issue:

• Check the Server’s FQDN and make sure this matches the domain configured on the Certificate.
• Check the CN and DNSName from the output of the command below:
keytool -list -v -keystore <keystore-directory>/.keystore

Cause

Hostname matching is done according to how the client identifies the host it's trying to access. If it's trying to access https://localhost/, then the certificate must be valid for localhost. If it's trying to access https://something-else.example, then the certificate must be valid for something-else.example, even if localhost and something-else.example are one and the same machine.

## Solution

We have two possible resolutions:

OR

• Fix the Server Domain/Hostname to match with the Certificate Domain/Hostname in the host file.
