Sonoff couldn't connect to MQTT

[Erwin033]

Hi,

I installed the latest toke Mosquito by docker at my Synology NAS.
Mosquitto is running normal, and I could connect with Domoticz. But isn't possible to connect MQTT with Sonoff Tasmota 6.1.1.c. The log at Sonoff replay's

11:49:12 MQT: Verbinding mislukt naar 192.XXX.XXX.XXX:1883, rc -2. Opnieuw proberen over 10 sec

Could anyone help me with this problem?
