Mosquitto 4.1 and 4.2 don't work after reboot Raspberry

When reboot my Raspberry with hass.io, the 19 sonoff switch with tasmota firmware, don’t reconnect to mosquitto broker, and keep it going disconnect and reconnect and generate this log:

[INFO] found mqtt_user on Home Assistant
1556611226: Client DVES_DC0970 already connected, closing old connection.
1556611226: Socket error on client DVES_DC0970, disconnecting.
1556611226: New client connected from 192.168.2.216 as DVES_DC0970 (c1, k10, u’mqtt_user’).

for all tasmota device!!!

I have the MQTT ENABLE option turned off for each switch, restarting the Raspberry, after which I have reactivated the MQTT ENABLE option of each switch one by one, and now it works.
Is there a solution or setting that can be set to avoid this problem?
Do I have to change some Tasmota or Mosquitto side settings?

Sorry for my English, I use google translator!
