Hi,
My hiveMQ broker allows connections only on port 8883 - encryption ON.
But I did further tests with Flespi.io. First, I use no TLS as in the tutorial. It works:
Then I try connect on flespi.io on port 8883. MQTT Explorer can connect with the following setting:
And I try multiple things on the router:
TLS ON/TLS insecure OFF:
TLS ON/TLS insecure ON:
TLS ON/TLS insecure OFF (Pre-Shared-Key based): same result.
TLS ON/TLS insecure ON (Pre-Shared-Key based): same result.
Thnak you!
