Hi, HTTP 505 from several browsers on only one PC points more toward a local proxy, VPN, web-filter driver, or security product than browser cache. Check Settings > Network & internet > Proxy and run netsh winhttp show proxy. Temporarily disable any VPN or antivirus web shield, and test the same site in a new Windows user profile. Also inspect the browser developer tools Network tab to see which server returns 505. Update or reinstall the PC's network driver from the manufacturer. If Safe Mode with Networking works, use a clean boot to identify the filter. The exact update KB and affected URLs would help narrow this down.
