What is the "NET::ERR_CERT_AUTHORITY_INVALID" error?

The "NET::ERR_CERT_AUTHORITY_INVALID" error occurs when there is a problem with the security certificate of the website you are trying to access. Every website has a security certificate that ensures the connection between your browser and the website is secure. When the certificate is not recognized or trusted by your browser, you will see this error message.

Possible Causes of the Error

There are a few common reasons why you might encounter the "NET::ERR_CERT_AUTHORITY_INVALID" error:

• Outdated browser: If you are using an outdated version of your web browser, it may not recognize the security certificate of the website.
• Incorrect date and time settings: If the date and time on your device are incorrect, it can cause issues with the security certificate validation.
• Antivirus or firewall interference: Sometimes, antivirus software or firewall settings can interfere with the validation of security certificates.
• Website certificate expired or not trusted: The website's security certificate may have expired or is not trusted by your browser.

Steps to Troubleshoot the Error

Follow these steps to troubleshoot and fix the "NET::ERR_CERT_AUTHORITY_INVALID" error:

Step 1: Update Your Web Browser

Make sure you are using the latest version of your web browser. Outdated browsers may not have the latest security updates and may not recognize the website's security certificate. To update your browser, follow these steps:

1. Open your web browser.
2. Click on the menu icon (usually three dots or lines) in the top right corner of the browser window.
3. Select "Settings" or "Options" from the drop-down menu.
4. In the settings/options page, look for the "About" or "Help" section.
5. Click on "About" or "Help" to check for updates.
6. If an update is available, follow the prompts to install it.
7. Restart your browser and try accessing the Web Telegram website again.

Step 2: Check Date and Time Settings

Incorrect date and time settings on your device can cause issues with the validation of security certificates. Follow these steps to check and correct your date and time settings:

1. Click on the clock or time display on your device's taskbar or system tray.
2. Select "Date and time settings" or a similar option.
3. Make sure the date, time, and time zone are correct.
4. If the settings are incorrect, toggle the switches to turn on automatic date and time or manually adjust them.
5. Restart your browser and try accessing the Web Telegram website again.

Step 3: Disable Antivirus or Firewall Temporarily

Antivirus software or firewall settings can sometimes interfere with the validation of security certificates. Temporarily disable your antivirus software or firewall and check if the error still persists. Please note that disabling your antivirus or firewall may leave your device temporarily vulnerable, so make sure to re-enable them after troubleshooting.

Step 4: Clear Browser Cache and Cookies

Clearing your browser's cache and cookies can help resolve issues related to website certificates. Follow these steps to clear cache and cookies:

1. Open your web browser.
2. Click on the menu icon (usually three dots or lines) in the top right corner of the browser window.

Step 5: Proceed with Caution (Advanced Users)

If none of the above steps resolve the issue, there may be a problem with the website's security certificate itself. Advanced users can try bypassing the certificate error by following these steps:

1. Open your web browser.
2. When you encounter the "NET::ERR_CERT_AUTHORITY_INVALID" error, click on the "Advanced" or "Advanced options" link.
3. Click on "Proceed to website" or "Continue to website" (the wording may vary).
4. Please note that bypassing the certificate error may expose you to potential security risks. Proceed with caution and only if you trust the website.
