Do you know what if the “Failed to Connect to server” occurred on your Linkus Mobile Client login page, what should you do?
Before blaming to awful network connection, I think you can check these three common causes first:
1. Check if the Linkus Server hasn't been enabled 00:33
2. Check if there's incorrect Port Forwarding on the router 00:54
3. Please ensure that you log in via IPv6 network 02:16
Next time when you meet this situation, please follow this video to find out the problem first. And if you have other solutions to deal with the sever connection error, please leave your comment and we can discuss it.
