Hi, I created a new account for HiveMQ cloud and a cluster with credentials but can not connect via mqtt-cli in windows. The message I got is “Server closed connection without DISCONNECT.” why? any suggestion

Hello Welcome to the HiveMQ Community forum. Glad to see you’re taking interest in HiveMQ and MQTT. Looks like you missed adding -s while connecting to the broker. Please add it and retry. Adding command for your reference: $ con -h <cluster-url> -p <port-number> -s -u <mqtt-credentials-userna…

Thanks a lot for your comment , but I’have really done exactly what you say, like documentation. Could it be because the payment section was not completed? I have not done it yet and enter credit card information?

Hi edouareg . Not yet, I use windows 7

Server closed connection without DISCONNECT Did anyone solve this? I am getting same thing from multiple clients. I installed mqtt-cli (on Windows 10); the “con” command does not connect. I’ve spent several hours trying various things: no luck. I switched to mqtt-cli because python-paho was a…

Server closed connection without DISCONNECT. I’m on Windows 11 and have the exact same issue. I have triple checked my address, port, and credentials and then some. All from the mqtt> prompt in the shell. The cluster is Connected with the green dot next to it.

I confirm the cluster itself is working. When I use the HiveMQ WebSocket Client browser tool the pub/sub works. I copy/paste the connection strings from my mqtt-cli connection string… so those are also correct. Odd though, my wireshark trace is shorter than I would have expected… with only 1 SSL m…

mqtt-cli problem SOLVED. Upgraded mqtt-cli worked. I got the link for the earlier version from the HiveMQ web site… can’t tell you how/where just now. But when I went to github directly, and found the latest… that version works. python-paho problem? I’ll work on that next.

My paho-python code is now also working. The API changed between mqtt 3 and 5, though the documentation for 5 has been sparse (to be kind). Specifically, there are now 5 arguments to the on_connect where there used to be 4.

Mike, what ae the 5 arguments? Even though I am using the cmd line it may have bearing on my issue. I use the format below from the HiveMQ docs. con -h -p -s -u -pw What would be the 5th? Thanks.
