How to Fix Windows Error 0x80072f8f

If you are encountering error 0x80072f8f on Windows, this guide will help you resolve it.

Quick Summary

Error code 0x80072f8f indicates a problem with secure connections, often related to SSL/TLS certificates. This typically happens when your system's date and time are incorrect, causing issues with certificate validation during secure connection attempts.

Common Causes

Incorrect Date and Time: The most common cause is an inaccurate system date or time. Secure connections rely on valid certificates, which have an expiration date. If your computer's clock is significantly off, the certificate validation will fail, leading to the error.
TLS/SSL Configuration Issues: Problems within the TLS/SSL configuration on your system can also trigger this error. Certain protocols might be disabled, or the system might be configured to not support the required protocols for the secure connection.
Firewall or Proxy Interference: Firewall or proxy server settings might be blocking or interfering with secure connections. The firewall settings might be overly restrictive, or the proxy server might not be configured correctly to handle SSL/TLS traffic.

Step-by-Step Fixes

Method 1: Correct Date and Time Settings

Step 1: Right-click on the clock in the bottom-right corner of your screen.

Step 2: Select 'Adjust date/time'.

Step 3: Ensure that the 'Set time automatically' option is enabled. If it is already enabled, toggle it off and then back on again.

Step 4: If you prefer to set the time and date manually, disable 'Set time automatically' and then click the 'Change' button to manually set the correct date and time.

Step 5: Click 'Change' to save the new date and time. Close the settings window and try again.

Method 2: Check TLS/SSL Settings

Step 1: Press the Windows key, type 'Internet Options', and press Enter.

Step 2: Go to the 'Advanced' tab.

Step 3: Scroll down to the 'Security' section.

Step 4: Ensure that 'Use TLS 1.2' is checked. You can also enable 'Use SSL 3.0' and 'Use TLS 1.0' and 'Use TLS 1.1' for compatibility, but TLS 1.2 is crucial.

Step 5: Click 'Apply' and then 'OK'. Restart your computer and try again.

Method 3: Disable Proxy Server (If Applicable)

Step 1: Press the Windows key, type 'Internet Options', and press Enter.

Step 2: Go to the 'Connections' tab.

Step 3: Click on 'LAN settings'.

Step 4: Uncheck the box that says 'Use a proxy server for your LAN'.

Step 5: Ensure that 'Automatically detect settings' is checked.
