Configuring proxy settings for WPS Cloud Sync is essential for users who are operating behind corporate firewalls or in environments where internet access is restricted through a proxy server.

Failure to define proxy details may cause the application to timeout or display connection errors, halting all cloud-related functionality.

WPS Cloud Sync relies on correct network routing — you must configure it explicitly to pass through your proxy rather than attempting a direct connection.

Start the WPS Office program from your desktop, start menu, or applications folder.

Go to the main menu bar, click on Tools, and then select Settings from the options that appear.

This opens the Options dialog box.

Look for the tab labeled Cloud Sync and click to enter its configuration area.

Here, you will find options related to your cloud account and synchronization behavior.

Scan for a setting titled Network, Proxy, or Connection.

If the proxy option is hidden, look for an "Advanced" or "More Options" link to reveal extra network controls.

Once in the proxy configuration section, you will be prompted to choose between using a direct connection or a proxy server.

Enable the proxy mode by selecting the corresponding checkbox or radio option.

The proxy address is typically a fully qualified domain name or IPv4

Your organization’s helpdesk or IT support team will supply you with the correct proxy address.

Enter the port number associated with the proxy server’s service.

Some enterprises use ports like 8081, 8082, or even 443 for HTTPS proxying.

If authentication is needed, check the box for "Use Authentication" or "Login Required."

Enter the credentials provided to you by your network administrator.

Authentication failures are often due to typographical errors, so review your entries before saving.

WPS Cloud Sync may ask you to select the correct proxy protocol from a dropdown menu.

For cloud sync, HTTPS is most commonly required — select it unless instructed otherwise.

Click "Save" or "Confirm" to finalize the proxy configuration.

WPS Cloud Sync will initiate a test connection to validate the proxy setup.

If the settings are correct, you should see a confirmation message indicating successful connection.

If connection fails, recheck the IP, port, and protocol — and ask IT to whitelist WPS Cloud Sync’s domains.

For users on macOS or Linux, the process is similar, but the menu structure may differ slightly.

Look under the "WPS Office" menu bar on macOS or the hamburger menu on Linux for "Preferences" or "Settings."

It is also worth noting that some organizations use automatic proxy configuration scripts, commonly known as PAC files.

In PAC-enabled environments, configure your OS proxy settings and leave WPS Office’s proxy fields blank.

On Windows, navigate to Control Panel → Network and Internet → Internet Options → Connections → LAN Settings.

WPS Office is designed to respect system proxy settings, so no additional configuration is needed.

Some antivirus programs may quarantine or block cloud sync applications — verify WPS Office is permitted.

Add WPS Office to the whitelist in your firewall, antivirus, or endpoint protection tool.

After completing all steps, restart WPS Office to ensure the proxy settings are fully active.

Verify sync functionality by creating a dummy file in your cloud folder and confirming it appears on another device.

Following this guide ensures WPS Cloud Sync operates reliably behind corporate proxies.
