Connecting confluence mobile app with client SSL/TLS certificate

Michal Kevicky

I wanted to connect to our confluence using Android app w/ SSL/TLS client certificate. Android internet browser is capable of connecting to the web version of confluence, but Android Confluence App not. Is there any way doing so? Will it be supported in any future release/update of the app?

Hi Michal,

According to our documentation on Confluence Mobile, SSL certificates are supported. I tried searching to see if there were any reported cases of the Android Confluence app not working with SSL/TLS, but I wasn't able to find any.

Here are the requirements for the SSL:

HTTPS and certificate requirements

In the latest version of the iOS and Android apps, you can connect to the app using either HTTP or HTTPS.

If you're using HTTPS your proxy must allow TLS 1.2 traffic. This is an iOS requirement that we've chosen to implement for both the iOS and Android apps to prevent confusion (for example where one device can log in, and another cannot).

Ideally, your certificate should be from a trusted Certificate Authority. If you have certificate that is self-signed, or from an unknown Certificate Authority (for example, you are your own CA), users may still be able to use the app by manually installing your certificate on their device. See our Knowledge base article for more information on how to do this.

Can you let me know what error message you're getting when you try to connect? If you're meeting all the requirements, have a look at the knowledge base article above for help connecting.

Let me know if you have any questions!

Regards,

Shannon

Hi Shannon,

I use own certification authority (not literally self signed). I have

my own CA only for issuing client certificates,
imported CA's public key certificate to my mobile,
imported client certificate to my mobile,
tested connection using mobile's web browser (chrome) - succeed.

Connection supports and works with TLS 1.0, 1.1, 1.2. It's published using valid Let's Encrypt certificate.

I have launched confluence mobile app, entered URL, hit NEXT button, got

Can't connect to your site
This could be because the URL is wrong, you need to use a VPN, or Confluence is unavailable.
LEARN MORE , TRY AGAIN

That's pretty much it.

Hi Michal,

Could you check the article Unable to connect to SSL services as well just to be sure that the proper certs are copied over? I know this helps most often when a valid cert isn't working as expected.

Failing this, I'll dig a bit more into it and see what else could cause this, but I haven't seen very many examples of this yet, unfortunately.

Hi Shanon,

meanwhile I tried multiple times, updated Confluence several times, actually running

Confluence v. 6.14.1 and 6.14.2
Confluence Server mobile app v. 0.2.21 installed from Google Play

Tested using

Google Pixel running Android 9
OnePlus 5 running Android 9

CA Certificate is installed in Trusted Credentials
Client certificates are installed in User Credentials with access mode set to "VPN and apps"

Reverse proxy (nginx, running TLS 1.2) have not logged any attempt to create SSL handshake with SSL/TLS client certificates, just got 403 for non-successfull attempt, while hitting /server-info.action

Regards,
Michal
