unable to migrate when TLS is used

With libvirt 6.9.0, qemu 5.1.0, and following configurations: libvirt: key_file = "/etc/ssl/libvirt/server.lan.key" cert_file = "/etc/ssl/libvirt/server.lan.crt" ca_file = "/etc/ssl/libvirt/ca.crt" log_filters="3:remote 4:event 3:util.json 3:rpc 1:*" log_outputs="1:file:/var/log/libvirt/libvirtd.log" qemu: default_tls_x509_cert_dir = "/etc/ssl/qemu" default_tls_x509_verify = 1 migration with tls: virsh # migrate vm1 qemu+tls://server2.lan/system --persistent --undefinesource --copy-storage-all --verbose --tls never succeeds. Progress stops typically at high progress amounts (95%-98%), and network traffic drastically drops as well (from 1 gbps+ to nothing). domjobinfo progress also stops. Without --tls migrations succeed without issues without any other changes to hosts or configurations.
