Good Day AamirshahSHAIK,
My name is Carlo, I am also using Windows 10 pc and community member like you. Let us work together to sort this out.
First you can check your internet speed using this link below and check if you are getting slow connection for us to check if the issue is with the computer or the network connection itself.

If you see slow speed using that test , there migth be an outage with your internet service provider.
If you see fast internet speed using that link , you can to restart your computer using cleanboot.

Once done restarting , try to download the ISO using a different browser if there's any and observe the connection.
I hope the information above helps.
Have a wonderful day ahead and stay safe.
Sincerely,
Carlo T.
