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. ** Affects: stunnel4 (Ubuntu) Importance: Undecided Status: New ** Project changed: launchpad => stunnel4 (Ubuntu) ** Summary changed: - stunnel breaks with openssl 1.1.1 + stunnel4 breaks with openssl 1.1.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864035 Title: stunnel4 breaks with openssl 1.1.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/stunnel4/+bug/1864035/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
