Unable to upgrade addon

Mark Murawski

I'm getting a nondescript error when trying to upgrade an addon:

 

Confluence: 6.5.0

Addon: HTML Elements (From 2.1.0 to 2.4.0)

 

The 'Check the logs' message is not super helpful so far.  The only thing so far I've found in the logs is the following:

 

/var/atlassian/application-data/confluence/logs/atlassian-confluence.log

 

2017-11-06 17:22:03,117 WARN [http-nio-8090-exec-9] [common.security.jersey.XsrfResourceFilter] passesAdditionalBrowserChecks Additional XSRF checks failed for request: http://doc.localnet:443/rest/plugins/1.0/ , origin: null , referrer: https://doc.localnet/plugins/servlet/upm , credentials in request: true , allowed via CORS: false
 -- referer: https://doc.localnet/plugins/servlet/upm | url: /rest/plugins/1.0/ | traceId: 06d53558cba50671 | userName: markm

Also, I think the error I'm having about the base url has something to do with it.  We're using https behind an apache proxy, and have all the correct settings in place in confluence server.xml according to the docs.  And yet there's an internal request to the non https url.  Which might be causing the problem?

 

     <Connector port="8090" connectionTimeout="20000" redirectPort="8443"
                maxThreads="48" minSpareThreads="10"
                enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
                protocol="org.apache.coyote.http11.Http11NioProtocol" proxyName="doc.localnet" proxyPort="443" schema="https" secure="true"/>

Also... Upgrades problems with addons (and the base url error) are new.  We didn't have problem ever when running confluence 6.2.1

Please see Cross Site Request Forgery (CSRF) protection changes in Atlassian REST

Per the error message you found, Confluence is seeing the request as coming from: http://doc.localnet:443/rest/plugins/1.0/ and the referrer as https://doc.localnet/plugins/servlet/upm. Since the port is different there is a cross site scripting error preventing you from updating the plugin.

I noticed a typo in the server.xml snippet in your description:

schema="https" should be scheme="https"

If that typo is in the actual server.xml it may be causing problems with the proxy support.
