I searched in internet and I found follow information:

This error seems to be coming from the kernel, from net/mac80211/mlme.c. The values for this reason_code can be found in include/linux/ieee80211.h under enum ieee80211_reasoncode, and value 3 means “WLAN_REASON_DEAUTH_LEAVING” (which doesn’t say much).

Log when this disconnected happen is follow:
