Hong Kong VPS (Virtual Private Server) or cloud host connection disconnection issues may cause unnecessary trouble to your work or applications. This problem usually has a variety of potential causes, but it can be fixed with some common methods. In this article, we will discuss the Hong Kong VPS connection dropped issue and how to solve it.

　　1. Check network connection:

　　​First, make sure there are no issues with your local network connection. Check your router, modem, and cable connections to make sure they are functioning properly. Also make sure there is no problem with your local computer's network adapter.

　　2. Server provider’s network status:

　　Sometimes, connection issues can be caused by network issues with the server provider. Visit the server provider's official website or support page to see if there are any notices or announcements about network issues. They usually provide information about the status of the server.

　　3. SSH session timeout:

　　If you use SSH to connect to your VPS, session timeouts may be a common problem. Extend the session timeout by changing the configuration of the SSH client to prevent disconnections. You can edit the ~/.ssh/config file and add the following content:

　　Host * ServerAliveInterval 60

　　This will send a keep-alive packet to the server every 60 seconds, preventing the session from timing out.

　　4. Use SSH persistent connection:

　　When connecting via SSH, you can use tools such as mosh (Mobile Shell) to maintain a persistent connection and restore the connection even if the network is interrupted. mosh is a more stable SSH alternative that works in unstable network conditions.

　　5. Check firewall and IP blocking:

　　Make sure that firewall rules on the server do not interrupt connections unnecessarily and avoid IP blocks on the local computer. If you use a firewall, review the rules carefully to make sure they are not blocking connections.

　　6. Server resource issues:

　　If your VPS is overloaded or has insufficient resources, it may cause unstable connections. Use a system monitoring tool such as top or htop to check server resource usage, especially memory and CPU.

　　Problems with disconnection when connecting to a Hong Kong VPS or cloud host can have a variety of causes, but can usually be resolved by checking the network connection, adjusting SSH settings, using persistent connection tools, and working with the server provider. Maintaining network and server stability is important to ensure smooth workflow and application operation.
