WIZ550S2E problem with MQTT

Question

I have a problem with establishing a connection with the mqtt broker. I uploaded the latest 1.3 firmware. If I do not give any subscribe and publish topic, the module connects correctly. Unfortunately, if I give it, the module connects and immediately disconnects, which blocks my entire broker and nothing works. I just noticed that the problem only occurs if you set up a Publish topic. When it is not set, everything works. I can send data via subscribe topic.

Hello, @dziob, I set up pub/sub topic for WIZ550S2E but it works well. (establishing a connection & send data) I think need to check the set options. Please capture and upload the configuration tool screen. I will check and respond. Thank you.
