hi
letsencrypt ssl does not support android 4 ??
my blog white ssl not open in adnroid 4 and older
how to solve this problem?
for this url
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.
