Connection failure with Mosquitto

[shimatai]

Which MQTT server did you use to run the example?

I'm trying to run this example using Mosquitto on its latest version. Mosquitto also supports MQTT versions 3.1 and 3.1.1

I added my Mosquitto server address on the Expert Advisors allowed URLs for WebRequest and I'm still getting connection failure.

EA on MT5 enables only port 80/443.

So you need to change the port in the example to 80 or 443

MQTT server also listens on port 80 or 443.

Change the port on the server from 1883/8883 to 80/443

sudo systemctl stop mosquitto

sudo apt-get install redir

sudo redir :80 :1883

sudo systemctl start mosquitto

Actually I did use standard 8883 port for SSL and 1883 for plain MQTT. You need to set the port permission in MT5 like xxx.xxx.xxx.xxx:1883

I used a local Mosquito Docker instance
