FreedomBox 21.9 (2021-09-18) removed support for SSLv3, TLSv1 and
TLSv1.1.

After upgrading to 21.9, I also found my tt-rss Android client (1.301-
fdroid) stopped working (SSLProtocolException:SSL handshake) on my
old phone frozen in time at Android 4.3.  I think older phones stuck at
older versions of Android are just out of luck.
