Downgrade was not so easy, because apt wanted to remove a heck of a lot of other packages. In the end I manually unpacked libsssl1.1_1.1.0g-2ubuntu4.3_amd64.deb and copied the files over. -> The problem was fixed.
So indeed the openssl library 1.1.1 caused these issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833039 Title: 18.04/Apache2: rejecting client initiated renegotiation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1833039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
