How to Fix the 'Bad Request: Please Update Your Browser' ...

Introduction A growing number of users encounter “Bad Request” messages when trying to reach Nintendo’s online storefronts or related web pages. Nintendo’s primary digital marketplace, the Nintendo eShop, launched on Nintendo Switch at system launch on March 3, 2017. For players and developers who rely on the eShop and Nintendo’s web services, the simplest fixes are often browser-compatibility steps or switching to the console’s native storefront. What the message means (rewritten quote) When a site responds with the prompt that originally read “Bad Request. Please update your browser,” it essentially indicates the web interface rejected the request and advised the user to use a more current browser version. In plain terms: the server refused the request and suggested updating the browser to a supported release. Verified context and platform background - Nintendo Switch: Released March 3, 2017, the Nintendo Switch unified Nintendo’s handheld and home-console strategies and includes a built-in Nintendo eShop app for digital purchases. Developers from Nintendo EPD to dozens of indie studios distribute games via the eShop. - Nintendo eShop: The eShop on Switch is the primary way to purchase and download digital games; it is maintained separately from Nintendo’s consumer-facing websites, which are accessed through web browsers on PCs and mobile devices. - Nintendo EPD and key titles: Nintendo EPD (Entertainment Planning & Development) is the primary internal developer behind flagship titles such as The Legend of Zelda: Breath of the Wild, which released alongside Switch on March 3, 2017, and remains a cornerstone example of first-party success on the platform. Practical, verified steps to resolve the error 1. Update your web browser to the latest stable version — modern web services require recent standards support. Major browsers (Chrome, Edge, Firefox, Safari) publish stable updates frequently. 2. Clear cookies and cached site data, then retry the site. 3. If the web storefront still shows an error, use the Nintendo Switch’s built-in eShop application to make purchases or manage downloads — the console’s app is the supported pathway for Switch transactions. 4. Ensure your console system software is up to date via System Settings > System > System Update. When to contact support If updates and cache clearing don’t resolve the issue, contact Nintendo Support with screenshots and exact error text. For developers or partners experiencing persistent API or storefront errors, submit a formal support ticket through Nintendo’s developer portal. Conclusion A “Bad Request” notice that recommends updating your browser usually points to client-side compatibility or stale session data. For Switch owners, the most reliable path for purchases and downloads remains the Nintendo eShop app on console; for web access, keeping your browser up to date and clearing site data resolves the majority of issues.
