The most likely reason is that your client is not sending valid MQTT packets. In this case, mosquitto will disconnect you immediately.

NAME
imqkeytool - generate a self-signed certificate for secure communication SYNOPSIS
/usr/bin/imqkeytool [-broker] [-servlet keystore_location] /usr/bin/imqkeytool -h DESCRIPTION
The imqkeytool utility generates a self-signed certificate for secure communication. The certificate can be used by a broker instance to establish a secure connection with a client, or by a Message Queue-supplied HTTPS servlet to establish a secure connection with a broker instance. An HTTPS servlet is an SSL-enabled varient of the HyperText Transfer Protocol that establishes a secure connection with a broker instance. Without an option, imqkeytool generates a self-signed certificate for a broker instance. imqkeytool uses command line options to specify whether the certificate is used by a broker instance or by a servlet. OPTIONS
The following options are supported: -broker Generate a self-signed certificate for the broker and places it in the Message Queue keystore. All broker instances running on a system must use the same certificate. -h Display usage help. Do not execute anything else on the command line. -servlet keystore_location Generate a self-signed certificate for an HTTPS servlet and places it in keystore_location. keystore_location refers to the location of the keystore. You should move this keystore to a location where it is accessible and read- able by the Message Queue HTTPS servlet to establish a secure connection with a broker. ENVIRONMENT VARIABLES
The following environment variables affect the execution of this command: IMQ_JAVAHOME Specify the Java 2 compatible runtime. When this environment variable is not set it defaults to /usr/j2se. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
/etc/imq/keystore Contains Message Queue keystore in which imqkeytool stores a self-signed certificate for brokers. ATTRIBUTES
