MQTT Port ( 1883 ) is always closed
#1
Hi,
We have 2 Logic Machine. Both of them same firmware. Same project. Same MQTT scripts. Same MQTT settings ( without encryption and anonymous connection ).
One of them 192.168.1.80 other 192.168.1.81 ip address.
I can communicate via MQTT Explorer with 81 address. But i cannot communicate with 80 address.
I scan with advanced port scanner. 
LM with IP Add 81 has http and 1883 port those are open.
LM with IP Add 80 has only http port. 1883 is not open.
I disabled and enabled and save everytime Enable MQTT broker without encryption setting.
I unistalled and installed MQTT Broker App. 
But everytime  1883 port looks closed in 192.168.1.80 LM

How can i open 1883 port , what can i do ?
