Hello,
I wand to get into the mqtt business. For test purposes I use a free cluster and have no problems to connect via the web client of hivemq. but when i try to connect via mqtt fx i can not get access. the error message is only “mqttexception: connection lost”.
tried some devices as well. like my esp32 with different binaries. all the same. Followed through the “get started” documentation. But no luck yet.
