Other possible causes include interference from firewalls or antivirus programs, unstable network adapters, problems with proxy settings, or power-saving events like putting your computer to sleep. Now that you know the causes, let’s discuss the solutions.
1. Disable or Uninstall Overprotective Antivirus Suites (if applicable)
If you’re using a third-party antivirus suite and you see the 10053 error code while using your email client (such as when sending or receiving emails with VPOP3), your antivirus software could be the reason. Some users have reported this problem most often with McAfee VirusScan and Norton Antivirus, although other antivirus software may also cause similar issues. If you think this applies to your situation, start by disabling real-time protection to see if the error stops. Most antivirus suites let you right-click their icon in the system tray and temporarily disable real-time protection. If simply disabling real-time protection doesn’t work, follow these steps to completely uninstall the conflicting antivirus software and remove any leftover files:
2. Perform a Complete TCP/IP Reset
If you’re seeing the 10053 error code immediately after a TCP/IP connection is aborted by Windows, this could be due to problems with network data transmission or corrupted settings. A full TCP/IP reset can often fix these kinds of issues.
3. Reboot or Reset Your Router/Modem
If the TCP/IP reset didn’t solve the issue, your current network settings might be the problem. Sometimes, Internet Service Providers (ISPs) assign temporary (dynamic) IP addresses that can conflict with SMTP settings, which may trigger the 10053 error code. To address this, you can either restart or reset your network device:
Restart the Router/Modem – This will refresh your network connection and update related settings.Reset the Router/Modem – This will clear all custom settings and restore your device to factory defaults.
We recommend starting with a simple restart first, and only doing a reset if restarting doesn’t fix the problem.
3.1. Restarting Your Router/Modem
Find the On/Off button on your router or modem (usually on the back).Turn it off and unplug the power cable from the wall outlet.Wait for at least one minute to allow any remaining power to fully drain from the device.
After waiting, plug everything back in, turn your device on, and wait for your internet connection to fully restore. Then, try to repeat the action that caused the error to check if the problem is resolved.
3.2. Resetting Your Router/Modem
If restarting the device did not work, you might be dealing with a deeper configuration problem inside your router or modem. In this case, a factory reset can help: Important: Resetting your device will erase all your custom settings, including saved PPPoE credentials, port forwarding, and any filtering options you’ve set up.
Locate the Reset button (a small button usually found at the back of the device).You may need a pointed object, like a paperclip, to press and hold the Reset button for about 10 seconds, or until all the device’s LEDs flash at once.
After the device resets and your internet connection is back, check if the 10053 error code is gone. If your ISP uses PPPoE, you’ll need to re-enter your username and password.
4. Disable Proxy or VPN Connection (if applicable)
If none of the previous solutions worked and you’re using a VPN client or proxy server to hide your connection, this is likely what’s causing the 10053 error. Many users have reported that disabling their VPN or proxy fixed this specific problem. Follow the steps below based on whether you’re using a VPN or a proxy:
4.1. Uninstall System-level VPN
4.2. Disable the Proxy Server
