I tried to install a TLS certificate for my MQTT architecture with mosquitto but when I try to publish a message such as mosquitto_pub --cafile ca.crt -h localhost -t hello -m world, the following error appears:

Error: Problem setting TLS options: File not found.

I have also tried to use this tls connection in python with paho library using the command client.tls_set("c:/etc/mosquitto/ca_certificates/ca.crt") but the following error appears:

context.load_verify_locations(ca_certs) FileNotFoundError: [Errno 2] No such file or directory

Do you have any idea of where is my error?
