After deploying the frontend code to the server, an error arises indicating a 404 Not Found at https://cowpte.com/authorized?code=b0gQqZ_5sTD3uH0XfUuZQQdDWrtpIsE5mi8DstGx3rGP6F5TLjlQX8vjChXKf1mw59zaktFzPwQ21hUN8HTmZ1oGTrhJtforqG9wKB1KCLRKKxoTtpmlYDeJ2-x3_VG1.

The issue appears to stem from Server-Side Rendering (SSR). The usage of BrowserRoute results in invalid URLs (404 Not Found) when the page is refreshed or accessed directly via the browser.

While HashRoute resolves this by making URLs functional upon refreshing or direct access, it introduces “/#/” into the URL, which is ugly. Thus, it’s not a preferred solution.

Given that BrowserRoute is exclusively for client-side routing, the solution lies in implementing server-side routing. This ensures that the server can appropriately handle direct browser requests.
