hostapd disconnect my clients when browsing (Raspberry Pi)

I’m trying to make my own Wi-Fi network using a Raspberry Pi 3 Model B (connected on Ethernet) and hostapd version 2.8-devel.

My config looks like that:

interface=wlan0
bridge=br0
hw_mode=g
channel=4
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
ssid=Minteck-Projects
wpa_passphrase=mysupersecretpassphrase
country_code=FR

And the problem is that when I access a YouTube video on my phone, the Wi-Fi is disconnected. But if I don’t access Internet (I tested by keeping on the Wi-Fi Settings page), the phone don’t get disconncted.
