My Android mobile app connects to [login to view URL] but, when users are on Wi-Fi, every call that should fetch levels or images stalls while all other endpoints work. Because the website and the admin panel load flawlessly, the server itself is reachable; only those two routes fail: /levels and the image URLs. I’d like you to dig through the app’s network traffic, compare it with the backend logs, and pinpoint why both Levels and Images API requests time out or error on Wi-Fi yet behave on cellular. Once the root cause is clear, you’ll need to patch either the client-side request logic (Retrofit/Volley/OkHttp—whatever you find inside) or the server configuration so that the endpoints respond reliably under any network. Deliverables • Written root-cause analysis referencing exact failing URLs and error codes • Code or configuration fix applied and documented • Proof of success: short screen recording or log capture showing levels and images loading over Wi-Fi on a stock Android device (API 30+) I’ll grant access to the repo and staging server as soon as we start. Let’s get these endpoints solid again.

Hi there, Your app's Wi-Fi-specific failures on the /levels and image endpoints point to a subtle networking or backend config issue - especially since the rest of the API works and the server is reachable. I'll inspect the app's network traffic (Retrofit, Volley, or OkHttp as found), tie it to backend logs, and identify why only these endpoints hang on Wi-Fi. Once the exact URLs and error codes are mapped out, I'll fix the root - whether it's client-side code or server configs - and document everything. You'll get a written root-cause analysis, the applied fix with notes, plus a screen recording or log capture from a stock Android API 30+ device showing both levels and images loading smoothly over Wi-Fi. To respect your constraints, I'll only touch the relevant code or config - no unrelated changes - and test thoroughly to confirm reliability before closing the fix. Sometimes, certain Wi-Fi setups reveal issues like large image payloads triggering timeouts or missed headers, so I'll watch for those edge cases. I'm motivated to build a strong reputation here and would value the chance to help. Access to the repo and staging server will let me get started right away. Is there any recent change or deployment you suspect triggered this issue? Best regards, Nataliya H.

Hi, I read your project "Fix Android API Failures". I'm a senior engineer (11+ yrs) specialized in API integration (REST/webhooks/OAuth, connecting third-party services end to end) — exactly what this needs. I've shipped my own products end to end and focus on reliable, maintainable delivery. How I'd approach it: 1) Quick chat to lock the exact scope and edge cases 2) Build in small, testable steps so you see progress early 3) Clean handover with docs Ready to begin immediately; I work async and communicate via chat. Ask me anything. Best, Chris

Hi, I have strong experience debugging Android networking issues involving Retrofit, OkHttp, Volley, API gateways, SSL/TLS, DNS, CDN, and server configuration. Since only the /levels endpoint and image URLs fail on Wi-Fi while the rest of the API works, this points to a specific networking or server configuration issue rather than a general connectivity problem. I'll systematically compare Android network logs, backend/server logs, request headers, SSL certificates, DNS resolution, redirects, CORS, caching, MIME types, and timeout behavior to identify the exact root cause. Once identified, I'll implement the appropriate fix—whether in the Android client (Retrofit/OkHttp configuration, image loading library, network security config) or on the server (Nginx/Apache, CDN, SSL, firewall, headers, or API configuration). Deliverables include: ✔ Detailed root-cause analysis with failing URLs and error codes ✔ Applied code/configuration fix with documentation ✔ End-to-end testing on Wi-Fi and mobile data ✔ Screen recording or log evidence confirming Levels and Images load correctly on Android API 30+ I can start immediately after receiving access to the repository and staging server and will provide regular progress updates until the issue is fully resolved.

Hi there, I can systematically diagnose and resolve the Wi-Fi-specific timeout issues affecting your `/levels` and image API endpoints on Android. By inspecting the HTTP/HTTPS request headers, Wi-Fi MTU/fragmentation settings, DNS resolution, IPv6 dual-stack handling, and OkHttp/Retrofit connection pooling or SSL handshake behavior against your backend logs, I will pinpoint the exact bottleneck causing these two specific routes to stall. Once identified, I will apply and document the necessary client-side logic patches or server/Nginx configuration fixes, and provide a clear root-cause analysis along with a log capture/video proof showing reliable loading over Wi-Fi on stock Android devices (API 30+). Would you like to grant access to the repo and staging logs so I can begin investigating the network traces? Best regards, Mohinder

Hi, This looks like a Wi-Fi-specific networking/configuration issue rather than a server outage. I'll trace the failing API calls, identify the root cause, fix it on the client or server, and provide tested proof that Levels and Images load correctly over Wi-Fi. Ready to start immediately. Thanks, Mohit

Hello. You need to fix Android API failures where only two endpoints—/levels and the image URLs—stall on Wi‑Fi while everything works on cellular. The server is reachable, so the issue sits between the app’s network layer and backend behaviour under specific network conditions. The goal is a precise root‑cause analysis and a clean patch on either client or server. Here is what I would do: Trace all network calls from the Android app (Retrofit/Volley/OkHttp) and compare them with backend logs to identify timeout patterns, DNS issues, caching headers or protocol mismatches. Check Wi‑Fi‑specific behaviours—MTU limits, redirects, mixed‑content blocks, image‑host CORS rules, or inconsistent SSL negotiation. Patch the client‑side request logic if needed (timeouts, interceptors, URL handling, image loading) or adjust server configuration so both endpoints respond consistently. Document the exact failing URLs, error codes and root cause, then provide a clean fix with comments. Deliver proof: logs or a short recording showing levels and images loading over Wi‑Fi on a stock Android device. I’ve resolved similar Android API failures where only certain routes break under Wi‑Fi due to subtle network or server‑side conditions, and can share examples once you reply. I have capacity now, and the first milestone would be a quick review of your current network stack. Would you prefer client‑side debugging first or server‑side log analysis first as the initial step?

Good day! Based on your requirements, I understand that your Android app is experiencing a network-specific issue where the /levels and image endpoints fail only on Wi-Fi, while all other API requests work correctly. I can investigate the complete request flow, analyze the app's network traffic alongside backend logs, identify the root cause (Retrofit/OkHttp, DNS, SSL, CORS, caching, firewall, or server configuration), and implement a reliable fix so the app works consistently across both Wi-Fi and mobile data. Questions: 1) Which Android networking library is currently being used (Retrofit, OkHttp, Volley, or another)? 2) Does this issue occur on all Wi-Fi networks or only on specific routers/ISPs? 3) Can you provide temporary access to the Android source code, backend logs, and staging server for debugging? I'd love to schedule a quick discussion to review the issue and start troubleshooting immediately. After identifying the root cause, I'll apply the fix, document the changes, and provide proof of successful testing with levels and images loading correctly over Wi-Fi. Thank You!

Hello, I can diagnose this by comparing the exact /levels and image requests over Wi-Fi versus cellular using Android/OkHttp logs, ADB evidence, and the staging server logs. I will check the failing URLs and error codes, DNS and IPv4/IPv6 behavior, TLS or cleartext restrictions, redirects, timeouts, caching, and any backend/CDN/firewall differences. I will apply the smallest reliable client-side or server configuration fix, retest on Android API 30+, and deliver the root-cause report, documented patch/configuration change, plus a short screen recording or log capture proving that levels and images load over Wi-Fi. I have hands-on Java, Android, API integration, software testing, and debugging experience. I can begin immediately and deliver within two days after receiving repository, staging-log, and test-account access. Please confirm whether the app is Java or Kotlin, which backend stack serves these routes, and whether you can provide a stock API 30+ test device or APK/account.
