# Your connection is not private on Android

> An outdated root store on older Android builds rejects chains that current desktop browsers accept.

## Why it happens on Android

 An outdated root store on older Android builds rejects chains that current desktop browsers accept.

## The fix on Android

 Set date and time to automatic, update Android System WebView and Chrome, then retry. If only old devices fail, reissue the certificate against a longer-established root.

## If that didn't fix it

 Android has its own failure mode, but Your connection is not private has a wider set of causes. The most common one overall is: The certificate expired (NET::ERR_CERT_DATE_INVALID).

 Renew the certificate and reload the web server.

## Check your own domain

 Running the check from outside your device separates a real certificate problem from a local clock or network issue in one step.
