Step 1: Check the Website URL

Incorrect system date and time settings can cause SSL certificate errors. Follow these steps to check and adjust your system time:

  1. Click on the clock or date in your taskbar.
  2. Select “Date and Time settings.”
  3. Ensure “Set time automatically” and “Set time zone automatically” are turned on.

Step 3: Clear Browsing Data

Stale or corrupted browser cache can sometimes cause SSL errors. Clear your browsing data as follows:

  1. Press Ctrl + Shift + Delete (or Cmd + Shift + Delete on Mac) in Chrome.
  2. Select “Browsing history,” “Cookies and other site data,” and “Cached images and files.”
  3. Click “Clear data.”

Step 4: Try Another Browser

To verify if the issue is specific to Chrome, try accessing the website using a different browser like Firefox or Microsoft Edge. If it works in another browser, the problem may be related to Chrome settings or extensions.

Step 5: Disable Extensions

Browser extensions can interfere with SSL certificates. Temporarily disable your Chrome extensions:

  1. Click the three vertical dots (menu icon) in the top-right corner of Chrome.
  2. Go to “More tools” and select “Extensions.”
  3. Toggle off all extensions by clicking the switch next to each one.

Try accessing the website again. If it works, re-enable extensions one by one to find the culprit.

  1. Click on the padlock icon in the address bar (left side).
  2. Select “Certificate (Valid)” or “Certificate (Invalid)” depending on the displayed status.
  3. In the certificate details, check the certificate’s issuer and validity dates.

If the certificate appears valid, contact the website administrator to ensure there are no server-side issues.

Step 7: Proceed with Caution (Not Recommended)

Warning: This step is not recommended unless you are sure the website is safe.

If you trust the website and are confident it’s safe to proceed despite the SSL error, you can bypass it:

  1. Click “Advanced” on the error page.
