I have a program that is refusing to accept the connection of a server no matter what the client code is below
I dont want to change the client's code because it used to work with a server until it was shutdown
I am trying to recreate the server.
I keep getting
MQTTnet.Exceptions.MqttCommunicationException: The remote certificate is invalid according to the validation procedure. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
