Step 1: Manually enabling and disabling DNS-over-HTTPS

• Go to the Open network and sharing centre option and click on it, or go to the control panel and click on it.
• Select the properties option from the drop-down menu.
• A pop-up message will appear, and you must select the “Internet Protocol version 4” option and then click on its attributes.
• Select “use the following DNS server addresses” from the drop-down menu.
• Replace 126.96.36.199 as the preferred DNS server and 188.8.131.52 as the alternate DNS server.
• After you’ve changed the servers, check the box that says “Validate settings upon exit” and then click “OK” to preserve the changes.
• Once you’ve closed the existing tabs, you’re done!

Step 2: Check your Firefox proxy Setting
This error may occur if your computer is set up to access the internet using a proxy server.
- Select the Options tab from the Tools menu in the Firefox menu bar.
- Now choose the Network tab from the Advanced panel.
- In the Connection area, click the Setting button.
- Connection Setting will appear as a popup on your screen.
Check if a Manual proxy connection is chosen in the Connection Setting box. If this option is chosen, your computer is set up to use a manual proxy server. As a result, double-check that all of the protocol fields (HTTP Proxy, SSL Proxy, FTP Proxy, SOCKS Host) are filled incorrectly. If not, make the necessary changes and click OK. We highly advise you to contact your network administrator if you have any issues throughout this procedure.
DO NOT make any modifications to the Manual proxy connection if it is not chosen. Simply exit the window and contact the network administrator.
Step 3: Check your Security Software for SSL Scanning
SSL Scanning, often known as SSL filtering, is a capability found in every security software. This feature is meant to prevent you from visiting a website with an expired SSL Certificate by mistake (this is an algorithm that is supposed to protect your data on any website it is installed on).
However, your security software may block you from visiting a website if the SSL Certificate for that website has been marked as expired or invalid by your security software.
To remedy this, go to the settings section of whatever security program you’re using and look for the SSL scanning feature. Once you’ve found it, uncheck the box that says it’s turned on.
After disabling this function in your security program, you should try re-accessing the page.
