Connection stability problem?

Hello,
could it be that there is currently is a stability problem with the MQTT-Broker? I can establisth a connection successfully using the MQTTX client (web and win64 installation). I tried all possible ports an connection types. It disconnects all the time after a few seconds of establishing a connection successfully. So it was not possible to subscribe any item. I do not think the problem is in my side... By the way, protocol verision 3.1.1 ist supported, 5.0 not, am I right?
Maybe you could give me a hint,
Best regards,
Manfred

I tried now the installed Windows version of MQTTX. All 4 connection types (web, tcp encrypted or not) are working fine. With the web-version https://mqttx.app/web-client# I could not establish connection. Also not with the HIVMQ client... MQTT Websocket Client
I was able to use the MQTTX web client. See screenshot below:
Note that you can only connect from using the same credentials from one "device" at a time. So, if you are using the same credentials from the desktop and the webclient at the same time, you will see disconnected/reconnected on both.
I have devices connected by MQTT for months now and the connection is rock solid.
It is likely that the connection is being disconnected when you try to subscribe to an invalid topic or to a topic the device is not authorized for. What is the topic you're subscribing to over the MQTT connection?
