▼ If the issue is related to your internet connection
(5) Restart your network equipment
Please restart your communication device (router or modem), then wait for a while before attempting to reconnect.

(6) Check with your Internet Service Provider
We recommend confirming with the following:
「Is the slow connection due to network congestion?」
「Are there any security features or services provided by your Internet Service Provider that could be affecting the communication?」

(7) Try a wired connection
If you are currently using a wireless (Wi-Fi) connection, interference from other devices may affect the connection.
Try switching to a wired (LAN) connection.
