What to do if Universal Plugin Manager (UPM) cannot connect to Plugin Exchange?

I have installed Confluence on a production system having a proxy. The browser has no problems accessing the Atlassian Plugin Exchange site and I have been able to install plugins manually.

However, Confluence Admin is not able to look for updates or new plugins to be installed from within the wiki.

It tells me

The Atlassian Plugin Exchange server is not reachable

(which is not the problem of the APE server since it is reachable from another wiki at another site) and

An unexpected error occurred. Please review the protocols.

Sometimes also

java.sql.ConnectionError: Timout (or so...)

This page


talks about permanently disabeling the connection but I'd rather try to get it working.

I saw proxy settings mentioned as a possible source of the problem:


Can anybody please explain how I (well, better the admin) should configure the proxy settings of Confluence (=> Tomcat?) to be able to access the plugin exchange?

Hi Matthias,

To configure Confluence to use a proxy you need to configure your System Properties in sentenv.sh (Linux) or sentenv.bat (Windows). Instructions on doing this are available at http://confluence.atlassian.com/display/DOC/Configuring+System+Properties In setenv.sh or setenv.bat you need to add the following:

-Dhttp.proxyHost=proxy.example.org -Dhttp.proxyPort=8080

where proxy.example.org is your proxy and http.proxyPort is the port that your proxy uses.

Full instructions on configuring web proxies is available at http://confluence.atlassian.com/display/DOC/Configure+Web+Proxy+Support+for+Confluence

Hope that helps,


is there an alternate way to push a bunch of plugins into the system ? (dropping them into a certain dir ?

You can the jar file from the Atlassian Marketplace and upload it on the Manage Addons
