Перенаправление журналов из rsyslog в graylog через tls

Я пытаюсь переслать логи из rsyslog в graylog через tls.

Конфигурация rsyslog:

# make gtls driver the default
$DefaultNetstreamDriver gtls
#
# # certificate files
$DefaultNetstreamDriverCAFile /etc/ssl/rsyslog/ca.pem
$DefaultNetstreamDriverCertFile /etc/ssl/rsyslog/rsyslog-cert.pem
$DefaultNetstreamDriverKeyFile /etc/ssl/rsyslog/rsyslog-key.pem
#
$ActionSendStreamDriverAuthMode x509/name
$ActionSendStreamDriverPermittedPeer graylog.mydomain.com
$ActionSendStreamDriverMode 1 # run driver in TLS-only mode
*.* @@graylog.mydomain.com:6514 # forward everything to remote server

Я создал необходимые сертификаты, как описано в документации rsyslog:

certtool --pkcs8 --generate-privkey --outfile ca-key.pem
certtool --pkcs8 --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem

certtool --pkcs8 --generate-privkey --outfile graylog.key.pem 
certtool --pkcs8 --generate-request --load-privkey graylog.key.pem --outfile graylog.request.pem
certtool --pkcs8 --generate-certificate --load-request graylog.request.pem --outfile graylog.cert.pem --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem

certtool --pkcs8 --generate-privkey --outfile rsyslog.key.pem 
certtool --pkcs8 --generate-request --load-privkey rsyslog.key.pem --outfile rsyslog.request.pem
certtool --pkcs8 --generate-certificate --load-request rsyslog.request.pem --outfile rsyslog.cert.pem --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem

Конфигурация Graylog

Все файлы сертификатов находятся в / etc / ssl / graylog / input-ca /

Вход серого журнала настроен следующим образом:

TLS cert file: /etc/ssl/graylog/input-ca/graylog-cert.pem
TLS private key file: /etc/ssl/graylog/input-ca/graylog-key.pem
TLS Client Auth Trusted Certs: /etc/ssl/graylog/input-ca

Но когда rsyslog отправляет сообщение журнала в garylog, я получаю эту ошибку:

Есть идеи, в чем может быть проблема?
