I had this issue after upgrade to ubuntu 22.04 with OPENSSL 3.2 and unbound 1.16.0
I compile ubuntu with this configures
unbound -V
Version 1.16.0
Configure line: --build=x86_64-linux-gnu --prefix=/usr --includedir=/include --mandir=/share/man --infodir=/share/info --sysconfdir=/etc --localstatedir=/var --disable-option-checking --disable-silent-rules --libdir=/lib/x86_64-linux-gnu --libexecdir=/lib/x86_64-linux-gnu --disable-maintainer-mode --disable-dependency-tracking --disable-rpath --with-pidfile=/run/unbound.pid --with-rootkey-file=/var/lib/unbound/root.key --with-libevent --with-pythonmodule --enable-subnet --enable-dnstap --enable-systemd --with-chroot-dir= --with-dnstap-socket-path=/run/dnstap.sock --libdir=/usr/lib --with-conf-file=/etc/unbound/unbound.conf.d/unbound.conf --with-conf-file=/etc/unbound/unbound.conf.d/unbound.conf --with-libhiredis --with-libevent --enable-checking PYTHON_VERSION=3.10
Linked libs: libevent 2.1.12-stable (it uses epoll), OpenSSL 3.0.2 15 Mar 2022
Linked modules: dns64 python cachedb subnetcache respip validator iterator
And without pythonmodule
The same error
I used this command to disable
SSL_read crypto error:0A000126
(#include <openssl/ssl.h> SSL_OP_IGNORE_UNEXPECTED_EOF)
And the debug: outnettcp got tcp error -1 (forwarding to stubby not working )
Any way to help
