症状

アドオンの管理/新規追加ページに移動すると、次のエラーが表示される。

The Atlassian Marketplace server is not reachable. To avoid problems when loading this page, you can disable the connection to the Marketplace server

Cause #1

Java は外向き接続を確立するときに、Marketplace のサーバー証明書を読む際に信頼を確立する必要があります。これを行うため、Atlassian Marketplace によって提供される証明書が信頼可能であることを示す証明書チェーンを Java のトラスト ストアで探します。このトラスト ストアはデフォルトでは JAVA_HOME/jre/lib/security/cacerts に配置されていますが、起動パラメーター -Djavax.net.ssl.trustStore でカスタマイズされた場所が定義されている可能性があります。

atlassian-jira.log には次のエラーが含まれる。

2013-10-29 14:30:17,194 WARN  [http-bio-7990-exec-5] user 870x497x1 1lzkc13 XXX.XXX.XXX.XXX,127.0.0.1 "GET /plugins/servlet/upm/marketplace HTTP/1.0" com.atlassian.upm.pac.PacClientImpl Error when querying application info from MPAC: com.atlassian.marketplace.client.MpacException: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

Jira が Marketplace へのアクセス時に信頼を確立できない場合、接続は却下され、管理者が Jira 内で Marketplace を利用することはできません。 これは、デフォルトの Java トラスト ストアが変更されたことによって有効な証明書チェーンが失われているか、Marketplace が提示した証明書がローカル プロキシによって改ざんされ、信頼できなくなったために発生します。

ソリューション #1

1. Download the Atlassian Marketplace certificates with the commands below

   keytool -printcert -sslserver marketplace.atlassian.com:443 -rfc >> marketplace.atlassian.com.crt
   keytool -printcert -sslserver marketplace-cdn.atlassian.com:443 -rfc >> marketplace-cdn.atlassian.com.crt
   keytool -printcert -sslserver api.media.atlassian.com:443 -rfc >> api.media.atlassian.com.crt
   

2. 証明書を Java トラスト ストアにインポートします。

Java 8

keytool -importcert -alias marketplace.atlassian.com -keystore <JAVA_HOME>/jre/lib/security/cacerts -storepass changeit -noprompt -file marketplace.atlassian.com.crt
keytool -importcert -alias marketplace-cdn.atlassian.com -keystore <JAVA_HOME>/jre/lib/security/cacerts -storepass changeit -noprompt -file marketplace-cdn.atlassian.com.crt
keytool -importcert -alias api.media.atlassian.com -keystore <JAVA_HOME>/jre/lib/security/cacerts -storepass changeit -noprompt -file api.media.atlassian.com.crt

Java 11

keytool -importcert -alias marketplace.atlassian.com -cacerts -storepass changeit -noprompt -file marketplace.atlassian.com.crt
keytool -importcert -alias marketplace-cdn.atlassian.com -cacerts -storepass changeit -noprompt -file marketplace-cdn.atlassian.com.crt
keytool -importcert -alias api.media.atlassian.com -cacerts -storepass changeit -noprompt -file api.media.atlassian.com.crt

3. Restart the Jira application. Certificates are loaded into the JVM on startup and such changes need a restart to take effect.

Cause #2

Jira establishes a connection/session to Marketplace during the application startup, in this scenario, Jira is able to access the Marketplace successfully, but eventually fails. As reported by some customers there are firewall appliances that set a default lifetime for TCP sessions. Some of these default to 15 minutes, and could compromise the connection to the marketplace.

ソリューション #2

increase the TTL for outgoing internet traffic from the Jira machine, and verify if the issue persists. Alternatively, allow the Jira host to bypass the outgoing connection proxy/firewall and verify.

Cause #3

Jira is configured with an outbound proxy server and the outbound proxy server is blocking outgoing requests sent from Jira to the Atlassian Marketplace.

To verify if this root cause applies:

• Look into the Jira application logs for an error similar to the one below. If you see that the error shows that Jira can't reach the Marketplace because it is failing to reach some IP address some hostname that is not the Marketplace, then it is an indicator that this root cause is relevant:

  2022-07-22 10:14:31,899-0400 pool-26-thread-2 WARN someuser 613x2051x1 k5zsja XXX.XX.XXX.X /rest/plugins/1.0/pac-status [c.a.upm.pac.MpacApplicationCacheManager] Error when querying application info from MPAC: com.atlassian.marketplace.client.MpacException: org.apache.http.conn.ConnectTimeoutException: Connect to <SOME_IP_ADDRESS>/<SOME_HOSTNAME>:8080 [<SOME_IP_ADDRESS>/<SOME_HOSTNAME>] failed: connect timed out

• Check the JVM startup used by the Jira application to see if Jira is configured with an outbound proxy. If you see parameters as in the example below, then it's an evidence that Jira is configured with an outbound proxy

  -Dhttp.proxyPort=8080
  -Dhttp.proxyHost=<SOME_IP_ADDRESS> OR <SOME_HOSTNAME>
  -Dhttps.proxyHost=<SOME_IP_ADDRESS> OR <SOME_HOSTNAME>
  -Dhttps.proxyPort=8080

ソリューション #3

Bypass any Atlassian URL in the outbound proxy configuration:

• Add the Jira's JVM startup parameters below in order to bypass any atlassian.com URL:
  

  -Dhttp.nonProxyHosts=*.atlassian.com

  
  

• Restart each Jira nodes, for this change to be effective

If the -Dhttp.nonProxyHosts is already used but with a different hostname, you can simply add *.atlassian.com to it, by using the pipe character as shown in the example below:

-Dhttp.nonProxyHosts=somehostname.com|*.atlassian.com
