Next.js offers several benefits for server-side rendering (SSR), including improved performance, SEO, and initial load times. SSR generates HTML on the server for each request, ensuring that search engines can easily index the content. It also reduces the time to first meaningful paint, providing a better user experience.

JWT tokens should be stored securely on the client side to prevent unauthorized access. Use `HttpOnly` cookies to store tokens, which prevents JavaScript access and mitigates XSS attacks. Ensure cookies are also marked as `Secure` to be sent only over HTTPS. Avoid storing tokens in local storage or session storage, as they are vulnerable to XSS attacks.

An API Version Mismatch error occurs when the client and server are using incompatible API versions. Ensure that both client and server are using the same version of the API, update versions as needed, and consult API documentation to manage version compatibility and avoid mismatches.
