Did you mean https://localhost:8787?

You are on localhost8787.com, a real website on the internet - not your machine. Your browser (or its search bar) probably turned localhost:8787 into a web search or a .com guess because nothing answered on that port.

Things to check

• Is your dev server actually running? Start it, then try http://localhost:8787/ or https://localhost:8787/ again.
• Is it listening on port 8787? Check the port in its startup output (8787 is the default for Cloudflare's wrangler dev, among others).
• Type the scheme explicitly - http://localhost:8787 - so the address bar cannot treat it as a search.
• If it still fails: is something else bound to the port (netstat -ano | findstr 8787 on Windows, lsof -i :8787 on macOS/Linux), or a firewall in the way?
