IPv6 mode

1. Basic understanding

Q1: What is IPv6? What are the benefits of turning it on?

IPv6 is a new generation of Internet protocol that mainly solves the problem of insufficient IPv4 addresses. After turning on IPv6, if your network supports it, the App can access the network through IPv4 and IPv6 at the same time, and the connection speed of some websites and services will be more stable.

Q2: Do I need to enable IPv6?

The default recommendation is to keep it off. It only needs to be turned on under the following circumstances:
  • The target website you visited only supports IPv6
  • Your home/office network is an IPv6-only environment
  • Customer service recommends that you enable it to troubleshoot the problem
If you are not sure, just keep the default settings and it will not affect normal use.

Q3: Why is the IPv6 switch gray and cannot be clicked?

This means that the network you are currently on does not support IPv6 (the operator or router has not assigned an IPv6 address). This is normal and not an app glitch.
  • The on/off status you previously set will be retained and will not be lost.
  • Once you switch to an IPv6-enabled network (such as changing to Wi-Fi or switching to mobile data), the switch automatically becomes available again

2. Use of switch

Q4: Where to turn on/off IPv6 mode?

Enter [My] in the lower right corner → [Other Settings] → Find the [IPv6 Mode] switch → click to switch.

Q5: Will turning on IPv6 consume more traffic?

Won't. IPv6 only changes the protocol format of data transmission, and the traffic accounting method is exactly the same as IPv4.

3. Connection failure

Q6: What should I do if I cannot connect to the VPN after turning on IPv6?

Please try the following steps in order:
  1. Turn off the IPv6 switch and reconnect to the VPN to see if it recovers.
  2. If you can connect after closing it, it means that the IPv6 channel of the current network is unstable and it is recommended to keep it closed.
  3. Try again after switching servers
  4. If the problem persists, please contact customer service and inform "Cannot connect after turning on IPv6"

Q7: What should I do if the network speed slows down after turning on IPv6?

Possible reasons:
  • The operator's IPv6 link quality is worse than IPv4 (common in some areas)
  • The current server is not optimized enough for IPv6
It is recommended to turn off the IPv6 switch directly and use the default IPv4 channel to restore normal speed.

Q8: The connection is successful but some websites cannot be opened?

Please try:
  1. Turn off IPv6 mode in settings
  2. Disconnect and reconnect VPN
  3. Revisit the site
If you can access it normally after turning off IPv6, it means that the IPv6 service of the website is unstable and you can use IPv4.

Q9: VPN disconnected after switching Wi-Fi or mobile data?

It is a normal phenomenon. When the network environment switches, the IPv6 support status may change, and the App will automatically reconnect. If it does not recover for a long time, please manually disconnect and reconnect.
