Quick Summary
The "net::ERR_CERT_REVOKED" error in Chrome indicates that the security certificate of the website you're trying to visit has been revoked by the issuing Certificate Authority (CA). This often means the certificate is no longer considered trustworthy and should not be used.
Common Causes
- Certificate Compromise: The most common cause is that the certificate's private key has been compromised, meaning unauthorized individuals could potentially use it for malicious purposes, such as impersonating the website.
- CA Revocation: The Certificate Authority (CA) that originally issued the certificate might have revoked it due to policy violations, security concerns, or other reasons deemed necessary to maintain internet security.
- Software Bugs/Glitches: Although rare, bugs in the browser or operating system can sometimes falsely report certificate revocation, even if the certificate itself is still valid. This is particularly true with outdated browsers or OS.
- Network Interception (Man-in-the-Middle): Malicious actors can intercept your internet traffic and replace a legitimate certificate with a revoked one to steal data. This type of attack, while complex, can trigger this error code.
Step-by-Step Fixes
Method 1: Clear Browsing Data and SSL State Show Steps ↓
Step 1: In Chrome, go to Settings (three vertical dots in the top-right corner).
Step 2: Click on Privacy and security, then Clear browsing data.
Step 3: Choose All time for the time range. Select Cookies and other site data, Cached images and files, and Clear SSL certificates.
Step 4: Click Clear data.
Step 5: Restart Chrome and try visiting the website again.
Method 2: Check Date and Time Settings Show Steps ↓
Step 1: Ensure your computer's date and time are set correctly. Incorrect date/time settings can interfere with certificate validation.
Step 2: If the date or time is wrong, correct it through your operating system's settings.
Step 3: Restart your browser after adjusting the date and time.
Method 3: Disable Antivirus/Firewall Temporarily (Use Caution!) Show Steps ↓
Step 1: Temporarily disable your antivirus software or firewall to check if it's interfering with the certificate validation process. Be extremely cautious when doing this, and only disable them long enough to test.
Step 2: Try accessing the website again after disabling the security software.
Step 3: If the error disappears, add an exception for the website in your antivirus/firewall settings. Don't leave your security software disabled permanently.
Method 4: Update Chrome Show Steps ↓
Step 1: Open Chrome.
Step 2: Click on the three vertical dots in the top-right corner and go to Help -> About Google Chrome.
Step 3: Chrome will automatically check for updates and install them.
Step 4: Restart Chrome to apply the updates.
Method 5: Check for Malware Show Steps ↓
Step 1: Run a full system scan with a reputable antivirus or anti-malware program. Malware can sometimes interfere with certificate validation processes.
Step 2: Follow the instructions of the antivirus program to remove any detected malware.
Step 3: Restart your computer after the scan and removal process is complete.
Method 6: Check Website Validity (If Possible and Appropriate) Show Steps ↓
Step 1: If the website is one you absolutely must access, and you trust the source inherently (e.g., internal company server), contact the website administrator and inform them about the revoked certificate issue. They need to update their certificate with a valid one.
Step 2: Do not enter sensitive information on a website displaying this error unless you are certain you understand the risks and have confirmed the website's legitimacy through a trusted out-of-band channel (e.g., phone call to the organization).
