SSL Handshake Error

[imagemaster]

We are using v20 and recently update the SSL certificate. It works fine from PWA and IOS. On the Adroid app it shows Ready for Calls but the green button is greyed out. The Teams, Contacts and Recents just keep spinning loading. I can make calls but I cannot receive any.

The Advance Log shows this error:

Any idea what can be causing this issue?

Hi,

We have released V20.0.0.36 Beta of the Android client today which should fix this issue:
https://www.3cx.com/blog/change-log/3cxphone-android-build-history/

You'd have to join the BETA program to get this update. Just launch the Play Store, search for 3CX, and while in the Apps information page (where you see Uninstall & Open) scroll down to where it reads "Join the Beta" and press "Join".

It may take a few minutes but once complete you will see the Update button available for you to install the latest Beta app.

At any time, you may leave the Beta program by following the same steps to where the app information page reads 'You're a beta tester' and tap on 'Leave'
