Fix 'Connection failure, please try again' error when adding Bitbucket Data Center to Jenkins Bitbucket server integration plugin.

Platform Notice: Data Center Only - This article only applies to Atlassian products on the Data Center platform.

Note that this KB was created for the Data Center version of the product. Data Center KBs for non-Data-Center-specific features may also work for Server versions of the product, however they have not been tested. Support for Server* products ended on February 15th 2024. If you are running a Server product, you can visit the Atlassian Server end of support announcement to review your migration options.

*Except Fisheye and Crucible

Cause

  • The Atlassian Bitbucket Integration plugin 4.0.0 uses okhttp(version 3.14.9) as its HTTP client, and as highlighted in the release notes of okhttp, since the release of okhttp 3.10.0, CN can no longer be used for hostname validation. This behavior was deprecated with RFC 2818 in May 2000 and was recently dropped from major web browsers. Since CN can't be used for hostname validation, the certificate must contain the matching SAN in it.

  • The hostname in this case couldn't be verified since the Bitbucket certificate did not have the SAN (Subject Alternative Name). As a result, the plugin returned the "javax.net.ssl.SSLPeerUnverifiedException: Hostname <hostname> not verified:" error.

Solution

Reconfigure the SSL certificate deployed at the Bitbucket(or Proxy/LB) to include the SAN in it. If the certificate is self-signed, it will need to be imported into the Java trust store of Jenkins as an extra step.
