Issue with connecting via certificates version 2.0.17

[hbibani]

The version of mosquitto is 2.0.17 and am using windows

I'm following this blog to create the certificates:

http:https://www.steves-internet-guide.com/mosquitto-tls/

openssl genrsa -des3 -out ca.key 2048
openssl req -new -x509 -days 1826 -key ca.key -out ca.crt
openssl genrsa -out server.key 2048
openssl req -new -out server.csr -key server.key
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 360

I changes the listener to:

listener 8883

and added the following lines:

cafile c:/certificates/ca.crt
keyfile c:/certificates/server.key
certfile c:/certificates/server.crt
tls_version tlsv1.2

And when I use the following windows equivalent

C:\mos>mosquitto_pub -h 192.168.1.41 -p 8883 -t test -m test --cafile c:/python34/steve/mqtt-demos/ca.crt --tls-version tlsv1.2

It says protocol error

And when I use mqtt explorer it says not authorized

Don't know what I'm doing wrong.
