Adding Jira as a trusted app: "An error occurred downloading a certificate"

[John Parsons]

We're trying to add a Jira instance as a trusted application to our Confluence instance and we're getting the following error.

"An error occurred downloading a certificate from: url"

Anyone run into this? I found an older post where someone just had to restart their server, but they didn't mention which. Is this likely some issue with the Jira instance, or Confluence? I was able to add Confluence as a trusted app into Jira without any problems.

Check your atlassian-jira.log. Often it'll have a more specific error message, then check that against the Knowledge Base. There's a section of configuration problems at Integration with Atlassian Applications (including Trusted Applications) Troubleshooting.

If there is indeed something in the logs when you try, post it here.
