Internet Explorer is old and doesn't support websites that use too-new features. Some alternatives are listed below. - [Microsoft Edge supported Operating Systems](https://learn.microsoft.com/en-us/deployedge/microsoft-edge-supported-operating-systems) lists [Microsoft Edge version 109](https://www.catalog.update.microsoft.com/Search.aspx?q=edge-stable-109) as the last version to support Windows 7. - The Chromium-based Brave browser last version to support Windows 7 seems to be [Release v1.46.144 (Chromium 108.0.5359.128)](https://github.com/brave/brave-browser/releases/tag/v1.46.144) - [Firefox users on Windows 7, 8 and 8.1 moving to Extended Support Release](https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support) lists Firefox version 115 as the last version to support Windows 7. See [Index of /pub/firefox/releases/](https://ftp.mozilla.org/pub/firefox/releases/). EDIT : Finally the problem wasn't with the browser but with the installed root certificates. Updating the [Root Certificates](https://support.microsoft.com/en-us/topic/support-for-urgent-trusted-root-updates-for-windows-root-certificate-program-in-windows-a4ac4d6c-7c62-3b6e-dfd2-377982bf3ea5) fixed the problem.
