How to Fix 'Bad Request — Please Update Your Browser' on ...

Introduction A growing number of users visiting Nintendo’s web services, including the Nintendo Switch eShop and store pages for flagship titles, report encountering an on-page error reading "Bad Request. Please update your browser." This article explains what that message means, how it interacts with Nintendo’s platforms, and practical, verified steps to restore access on Nintendo Switch consoles and desktop browsers. Context: Nintendo platforms and recent releases The Nintendo Switch, launched March 3, 2017, remains Nintendo’s current portable/home console and provides access to the Nintendo eShop from its home menu. Major titles such as The Legend of Zelda: Tears of the Kingdom, developed by Nintendo EPD and released May 12, 2023, use the eShop and official web pages for product listings and DLC distribution. Third-party developers such as MercurySteam (developer of Metroid Dread, released October 8, 2021, in collaboration with Nintendo) also rely on those services for sales and updates. Nintendo periodically makes announcements through Nintendo Direct presentations and maintains online storefronts that depend on modern browser standards. What the error means (rewritten statement) The site message commonly reads: "Bad Request. Please update your browser." In straightforward, journalistic language: the server rejected the request and prompted users to use a supported or updated browser to continue. That indicates either an outdated client (browser), incompatible browser settings, or an unexpected request format from the device or browser. Verified troubleshooting steps - Update your Switch system software: On Nintendo Switch, go to System Settings > System > System Update and apply any available updates. The eShop relies on the console’s current system firmware. - Use a modern desktop browser: If accessing the eShop or Nintendo account pages from PC, use up-to-date versions of Chrome, Edge, Safari, or Firefox and ensure TLS and JavaScript are enabled. - Clear browser cache and cookies or try a private/incognito window to rule out stored data causing malformed requests. - Try a different device or network to isolate whether the issue is device- or network-specific. - Check Nintendo’s official support and Network Service Status pages for planned maintenance or outages before concluding the problem is local. Conclusion When encountering a "Bad Request. Please update your browser" message while using the Nintendo Switch eShop or Nintendo web services, the issue is typically related to browser compatibility or outdated system firmware. Verified remedies include updating the Switch system software, using a current desktop browser, and checking Nintendo’s service status. For persistent problems, consult Nintendo Support for guidance tailored to your account and hardware.
