Problem using replit

When i wrote some code in html and run the code it gives this message"Web page not available
The web page at https://1c68d3a2-ebe7-4dcb-97c6-ac90816f4a33-00-ir2arur1fdaz.sisko.replit.dev/__replco/devtools_wrapper.html?initialPath=%2F&id=%3Arr%3A could not be loaded because:

net::ERR_NAME_NOT_RESOLVED"
I waited for so long and my internet speed is good but always it’s the same

could you give a link to the repl that gave you the error? It could be something in the code is preventing the web page loading.
