cannot establish secure connection

[carrotmuseum]

When I try access some websites (not all) using my ZTE Blade mobile, using wireless or data, I keep receiving the message - Cannot establish secure connection. I can get connected e.g. google and many other sites. But for example twitter - no.

Not changed any settings and downloaded any new apps.

It's an old phone Android 2.2 everything else works fine. Are there some settings I need to adjust?

Tried re-boot of router. Cleared cache and temp files. Play store does not have compatible app for twitter or chrome.

I can access Twitter and all other sites when I use a laptop and the same router.

No, there's nothing you can do to make the phone connect to those sites. It's an incompatibility between an old phone's web browser and the site's security certificate. The only "solution" is to get a new phone.
