The sign-up flow in my React Native Android app currently dies with a generic “server connection” message the moment a new user hits Create Account. The backend that receives that call is a hand-rolled PHP API sitting on a LAMP stack. Everything else in the app still talks to the API just fine—only the registration endpoint is misbehaving—so I need a full-stack set of eyes on both sides of the wire. Here’s what you’ll actually do for me: • Trace the request in the React Native code, confirm the payload, headers, and route. • Inspect the matching PHP endpoint, including any auth guards, DB inserts, or third-party calls it triggers. • Identify and eliminate the root cause of the connection failure (timeout, auth, database, mis-routing—whatever you find). • Patch the code, test end-to-end on a real device and emulator, then provide a concise summary of what you changed and why. Acceptance criteria – A new user can register from the Android build without error. – The account record lands in the database and immediately authenticates on login. – All existing functionality remains untouched. You’ll have SSH and repo access as soon as we start; I’m on Slack for quick questions and can run server-side commands or re-deploy as needed. Let me know your estimated turnaround once you’ve glanced at the code.

⭐⭐⭐⭐⭐ Hello Valuable Client, CnELIndia, with Raman Ladhani’s full-stack expertise, can help you resolve this issue end-to-end. Our first step will be tracing the React Native registration request to validate payload, headers, and endpoint routing. We’ll then debug the PHP API on your LAMP stack, reviewing auth logic, DB insertion routines, and any third-party dependencies that could be causing the failure. Once the root cause is identified—whether timeout, database constraint, or misconfigured route—we’ll implement a clean patch. Following that, we’ll test thoroughly on emulator and real devices to confirm new users can register, records persist in MySQL, and immediate login works seamlessly. We’ll also ensure regression testing so all other app functions remain intact. Finally, you’ll receive a concise technical summary of the changes for transparency and future reference. With SSH and repo access, we can deliver a reliable fix quickly while keeping you updated on Slack throughout the process.

✋ Hi there. I can fix your React Native registration flow and get the sign-up process working smoothly again. ✔️ I have strong experience working with React Native apps connected to PHP APIs on LAMP stacks. I’ve debugged and resolved similar issues before where one endpoint failed while the rest of the API worked fine. I’ll start by tracing the request from the app, validating headers and payloads, then reviewing the PHP endpoint for auth checks, DB inserts, or routing errors. ✔️ My strategy is to replicate the issue on both emulator and device, log the full request-response cycle, and pinpoint whether the failure is coming from network handling, server configuration, or application logic. Once identified, I’ll patch the code, retest the flow end-to-end, and confirm that a new account can be created, saved in the database, and logged in immediately. ✔️ I’ll make sure the fix doesn’t affect other parts of your app. At the end, I’ll provide you with a clear summary of the problem and the exact changes made so your codebase stays easy to maintain. Please click the ‘Chat’ button so we can discuss your project in detail and get started. Looking forward to working with you! Best regards, Mykhaylo
