VESYNC APP TROUBLESHOOTING

My air fryer isn't connecting to the VeSync app.
• During the setup process, you must be on
a secure 2.4GHz WiFi network. Confirm
that the network is working correctly.
◦
Make sure the WiFi password you
entered is correct.
◦
There should be no spaces at the
beginning or end of the password.
◦
Test the password by connecting
a different electronic device to the
router.
◦
If you're manually typing in the SSID
and password, double check that both
are entered correctly.
• Your air fryer should be within 164 ft /
50 m visible range of the router. Your
phone should be as close as possible to
your air fryer.
• Your router may need to be at a higher
location, away from obstructions.
• Make sure your air fryer and router are
away from appliances (such as microwave
ovens, refrigerators, electronic devices,
etc.) to avoid signal interference.
• If you're using a VPN, make sure it's
turned off while setting up your air fryer.
• Reset the air fryer (see page 29).

Connecting for Advanced Users
Try these suggestions for checking
your router configuration.
• Make sure you don't have too
many devices connected to your
router on the 2.4GHz band. Your
router may limit the number of
devices you can connect. Turn off
this limit in your router settings.
• Disable portal authentication. If
portal authentication is enabled,
the air fryer will not be able to
access your WiFi network, and
setup will fail.
Note: Portal authentication requires you to
sign in to your WiFi network through a web
page before you can use the internet.
• Make sure that the router DHCP
service is enabled. This service
is used to assign an IP address to
your air fryer. If the DHCP service
is disabled, the air fryer will not be
able to obtain an IP address and
will not be able to connect to your
WiFi network.
• Disable URL filtering.
• Open firewall ports. Your air fryer
needs to use ports 443, 4005, 1883,
and 17273 to connect to your WiFi
network.
• Disable wireless MAC address
filtering.
• Confirm that your ISP has not
disabled ports 1883 or 17273.
