Problem

The Confluence Data Center and Server mobile app shows one of the following errors when user tries to log in or connect the app to an existing Confluence site, or displays a desktop version of Confluence after logging in.

Cause

This error often occurs if you’re using a proxy server, which might modify the response returned to the mobile app. If the response doesn’t include all headers or cookies required by the app, you either won’t be able to log in at all or will see a desktop version of Jira instead of the mobile one.

This problem affects earlier versions of the Confluence mobile app connecting to Confluence 7.5 and earlier. 

Diagnosis

To check if the mobile app returns all required headers, you can make a HEAD request with the URL: <your-instance-base-url>/server-info.action.

Solution

If you're using the latest version of the app, and connecting to Confluence 7.6 or later, you no longer need to allowlist headers. If you're seeing the desktop view in the app, see The Confluence Data Center and Server mobile app displays a desktop version of Confluence after log in.

If you're using an older version of the app to connect to Confluence 7.5 or earlier, the response should include all of the following headers. If it doesn’t, make sure to allowlist the missing ones on your proxy server.

instance-name: <name>
confluence-base-url: <base-url>

mobile-supported-version: true
mobile-plugin-enabled: true
push-notification-enabled: true
