You leave a lot of the imagination, like if you are using a apache rewrite/mod proxy in front of it, but in short i noticed that if your server URL is set to, but you are accessing it through https://confluence/ this could create problems specifically with UPM upgrades.

If you are using a mod proxy, and is using the correct and full server-url but missed out on the proxy statements in server.xml, this behavior can be seen too.

A fast fix (which does not require a restart) can be to switch the server url to the none SSL port (normally 8080, but please check this) by setting the application url to, surf to that URL, update UPM, and switch it back again.

If little or nothing of this corresponds to your setup, add more details and ill do what i can to help you out.



Thanks a lot for your reply.
Our JIRA is installed on our own internal server and i've installed JIRA and Confluence on the same machine with this doc :

Perhaps it's the cause of my trouble ?

What do you think about it ?
