Is it true that letsencrypt no longer supports older Android?

Hi @zst42

that's not Letsencrypt, that's your configuration - see https://check-your-website.server-daten.de/?q=arzunkadeh.com#connections

You have disabled Tls.1.0 and 1.1, that's good.

But - see SSL Server Test: arzunkadeh.com (Powered by Qualys SSL Labs)

Not simulated clients (Protocol mismatch)

Android 2.3.7 No SNI 2 Protocol mismatch (not simulated)
Android 4.0.4 Protocol mismatch (not simulated)
Android 4.1.1 Protocol mismatch (not simulated)
Android 4.2.2 Protocol mismatch (not simulated)
Android 4.3 Protocol mismatch (not simulated)

So older Android versions (only with 1.0 or 1.1) can't connect your site.
