iOS 13 incompatible with Confluence

Question

Dear Confluence community,

I used Confluence Server App on iOS 12 without any issues. Talking about App version 1.4.1.
I used it with Confluence 7.1.1 hosted by myself (ubuntu Server 18.04), using HTTPs/SSL. I installed the root cert on my iOS 12 device and installed the exact same root certificate on my iOS 13 device.

When trying to connect to the server, the message "Can't get a secure connection" is showning up immediately. Even when uninstalling confluence, uninstalling the profile/cert, reinstalling the cert (and trusting it of course) and reinstalling confluence, the same issue happens. So everyone can not use the Confluence app when he upgraded to iOS 13 unfortunately.
iOS 12 still works perfectly. Can I do something about the 13-issue or does Atlassian need to update the app?
Many thanks and best regards
Wolfgang

Hi Wolfgang,

Thank you so much for confirming that. I've suggested the following update to our documentation as a result:

* CONFCLOUD-68883 Update Mobile app documentation w/ new security requirements certificates in iOS 13

Let me know if you have any questions about that!

Regards,

Shannon

The App is not the issue. Your server certificate has to meet the Apple requirements. Mine did not. Now it does. Everything works fine. 
perhaps you should communicate that to avoid further questions.

Many thanks and best regards.

Wolfgang,

If you're able to confirm that your SSL meets the new requirements, we can proceed from there. I haven't yet heard of any other users having issues with iOS 13 and the mobile app.

It appears to me that problems may occur in Safari 13.0 according to their article. It's best to narrow-down any issues with Apple's new requirements before we can proceed.

Regards,

Shannon
