Confluence behind LoadBalancer with another domain results in XSRF error

If you have an atlassian confluence running, which is published by a loadbalancer or reverse proxy using another domain, you might run into an XSRF error.

Example

Confluence FQDN: somehostname.domain.tld
LoadBalancer Confluence FQDN: confluence.domain.tld

Some actions like uploading your profile picture (https://confluence.domain.tld/users/profile/editmyprofilepicture.action) do not work. You'll receive an generic error from the confluence page (see red box of the screenshot below). If you check the HTTP Header response, you'll see XSRF check failed. It is caused by the confluence cross site request forgery (CSRF) protection.

Confluence XSRF Error

Solution

Edit confluence server.xml and add the FQDN from the LoadBalancer or reverse proxy.
