問題

Setting Bitbucket Server Webhook to Jenkins results in an error when running the "Trigger" Jenkins test. The following appears in the UI:

Error: Jenkins response: <HEAD><TITLE>Unknown Host</TITLE></HEAD> <BODY BGCOLOR="white" FGCOLOR="black"><H1>Unknown Host</H1><HR> <FONT FACE="Helvetica,Arial"><B> Description: Unable to locate the server named "<em>illin3305</em>" — the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.</B></FONT> <HR> <!-- default "Unknown Host" response (504) --> </BODY>

The following is displayed on the atlassian-bitbucket.log:

2016-02-10 11:35:48,452 INFO  [WebHookProcessor:thread-1] ausername @74KRR2x695x264x0 1km74r 127.0.0.1 SSH - git-receive-pack '/gttoj/mygittestproject.git' c.a.b.p.h.i.RequestFactoryWebHookProcessorWorker Invalid response from hook 'http://yourjenkins.com:42500/jenkins/bitbucket-hook/', repository ID '1', status: '504' / 'Unknown Host'

The host above can be pinged from the machine hosting Bitbucket Server, though.

 

診断

環境

  • Check your JVM for outbound proxy configuration. Are there any parameters like the one below configured?

    -Dhttp.proxyUser
    -Dhttp.proxyPassword
    -Dhttp.proxyHost
    -Dhttp.proxyPort

診断ステップ

  • pinging the address from the server hosting Bitbucket is an excellent clue to see if the domain can be resolved thus confirming the outbound proxy is playing a role here.

原因

JVM parameter for outbound proxy configuration could be causing this issue.

ソリューション

In order to fix this, please configure a parameter to stop requests from the application from going through the Outbound proxy.
