Hi,

We're using the Samsung email app on Android, using the Exchange support. Today we're getting a popup 'Certificate not secure for 'email address''.

When we view the certificate the common name is for ubnt  and Ubiquiti Networks inc.

The certificate expired 29/04/2018. We're not using Ubiquiti network gear here. We get the same error if we use WiFi or 4G.

Any ideas?

Cheers
