If you want to use certless TLS communication, there is no need to configure DefaultNetstreamDriverCAFile, DefaultNetstreamDriverCertFile or DefaultNetstreamDriverKeyFile. See our sample configuratrions from the testbench: https://github.com/rsyslog/rsyslog/blob/91885676001c9df1c2c91514d144cf71755d5d14/tests/sndrcv_tls_gtls_serveranon_gtls_clientanon.sh
I would recommend to switch over to the openssl (ossl) driver which gives us way more detailed error messages. My guess is that rsyslog and your NAS are not finding a shared cipher.
