The "Gateway Timeout" error is an HTTP status code that indicates the server, acting as a gateway or proxy, did not receive a timely response from an upstream server while attempting to fulfill the request. In the context of Vercel, which is a cloud platform for deploying web applications, it typically means that there was a timeout when Vercel tried to communicate with the backend server or API that OnlyWaifus relies on. When a request is made to a web application hosted on Vercel, Vercel acts as a proxy between the client and your application's backend. It forwards the request to your backend server or API and then waits for a response. If the backend server takes too long to respond, Vercel may time out and return a "Gateway Timeout" error to the client. So I would suggest you wait for a while and then try reloading the page again and OnlyWaifus should be back at working again. Happened to me as well a few times. Note: This issue has been fixed now!
