MQTT fail to connect

Configuration
1

I am about to pull my hair out. I am trying to simply setup a sonoff basic and I think I have done everything correctly but obviously not.
My sonoff switch has this in the console.

03:29:38 MQT: Attempting connection...
03:29:38 MQT: Connect failed to 192.168.1.50:1883, rc 5. Retry in 10 sec

03:30:33 MQT: Attempting connection...
03:30:33 MQT: Connect failed to 192.168.1.50:1883, rc 5. Retry in 10 se

The console of my MQTT server in HomeAssistant is this.

1574735604: New connection from 192.168.1.53 on port 1883.
1574735604: Socket error on client <unknown>, disconnecting.

1574735626: New connection from 192.168.1.53 on port 1883.

I cannot figure out what I have done wrong.
Thanks in advance for the help.

I actually don’t know what I did, but it works. I kept starting from scratch, i.e. new SD card, and finally it worked.
