Public bug reported:
stunnel4 breaks with openssl 1.1.1 which supports TLS 1.3. This bug has
been introduced with the migration from openssl 1.1.0 in one of the last
point releases.
I get errors when a Windows stunnel client connects to the stunnel4
daemon:
Feb 20 14:10:03 peterpan.neverland stunnel[24427]: LOG3[0]: s_connect: connect
::1:3128
: Connection refused (111)
This can be fixed when I manually add "MaxProtocol = TLSv1.2" to
/etc/ssl/openssl.conf, showing that TLS 1.3 introduced by openssl 1.1.1
is the culprit.
Probably stunnel4 needs an update.
