Hi @quabal666

It is a pleasure to welcome you to the community. We are always happy to support new users in their journey of learning MQTT and the HiveMQ platform.

We have reviewed your query and understand that you are encountering difficulties with establishing a connection. To effectively troubleshoot this matter, it is often necessary to utilize a tool that can produce detailed diagnostic logs. While MQTT Explorer is an excellent client, the MQTT-CLI is particularly well-suited for debugging connection issues due to its verbose output capabilities.

To help resolve the issue you are experiencing, we kindly suggest the following steps:

  1. First, please ensure that user credentials have been created for your MQTT client. It is also essential to verify that the configured permissions allow the client to subscribe to the necessary topics.

  2. Next, please attempt to verify the connection using the MQTT-CLI with the command provided below. The --debug flag will generate a detailed log of the connection attempt, which is instrumental in identifying the source of the problem.

mqtt subscribe --topic '#' --qos 1 --host 6915776f25504a67addcf473874c70c5.s1.eu.hivemq.cloud --port 8883 --secure --user qubal666 --password YOURPASSWORD --debug

Should the connection fail, the output from this command will typically indicate the specific reason. This information will be invaluable for further diagnosis.

We hope this guidance is helpful. Please do not hesitate to share the output if the problem persists.

Kind regards,

The HiveMQ Team
