You answered my question before I even got to ask it! I replaced the
SSLProtocol all -SSLv3 -TLSv1 -TLSv1.1
But nothing changed, even after:
Not even after a full reboot. I'm still getting the same SSL errors and
the output of the tests from ssllabs.com still give me an A+ with the same
The only other reference I found to SSL security is in freedombox.conf:
# Disable ciphers that are weak or without forward secrecy.
But I have no idea what to do with this. Should I just comment it? or

This "new" phone is so locked up that I don't think it can even be
rooted (Samsung Galaxy mega GT-I9152) but the old one (Galaxy S SGH-T959) is
already rooted and newer versions of lineage OS are available, so I'll

Thank you very much for taking the time to reply. I learned something
