My mobile app, PLIGNET, is an unlimited-internet VPN built for Android. Users can connect without trouble, but the underlying VPN/WebSocket session silently dies after 30 minutes to an hour while the UI still shows “connected.” Signal strength and network type don’t seem to matter. I need a seasoned Android developer who can: • Trace and pinpoint the exact cause of the premature disconnect—whether it’s a foreground-service timeout, keep-alive misconfiguration, socket heartbeat problem, or something deeper in the VPN service implementation. • Implement and test a reliable fix so the tunnel stays alive indefinitely under normal conditions. • Provide a concise technical report summarizing what you found, what you changed, and how to reproduce the before/after behavior. Key context: – Platform: Android only (no iOS codebase involved). – VPN stack relies on WebSockets, so experience with okhttp, Netty, or similar libraries—as well as Android VpnService, WorkManager, and power-management nuances—is highly valuable. – You’ll have access to the current source, build scripts, and any backend endpoints needed for debugging. Deliverables: 1. Updated, compilable Android project with the stability fix applied. 2. Step-by-step notes or commit messages explaining each significant change. 3. APK (or Play-ready bundle) demonstrating a sustained connection through at least a 2-hour continuous test. Let me know your estimated timeline and cost, along with any initial questions you need answered before you dive in.

Hi, I can help resolve the issue with your PLIGNET VPN app, where the WebSocket session prematurely disconnects while the UI shows "connected." I will carefully analyze the underlying code to pinpoint the cause, whether it’s a foreground service timeout, misconfigured keep-alive settings, or an issue within the VPN service implementation itself. Once identified, I will implement and test a reliable fix to ensure the VPN tunnel remains stable and connected indefinitely under normal conditions. I’ll also provide a concise technical report detailing the cause, the fix, and how to reproduce both the original issue and the corrected behavior. My experience with Android VpnService, WorkManager, WebSocket libraries like okhttp, and power-management nuances will be key to resolving this. Best, Justin

Hi, I’m interested in diagnosing and fixing the disconnect issue in PLIGNET. I have solid experience with Android VPN apps, long-running foreground services, and WebSocket-based tunnels where the UI remains “connected” but the underlying session silently dies. I can help by: • Tracing the exact cause of the disconnect (foreground service lifecycle, keep-alive/heartbeat, socket idle timeout, Doze/App Standby, or VpnService handling) • Fixing the root issue so the tunnel remains stable for long sessions • Verifying the solution with extended real-world testing (2+ hours) • Providing a concise technical report explaining the cause, fix, and before/after behavior I’ve worked with Android VpnService, WebSockets (OkHttp), background execution limits, power management, and network edge cases across different Android versions. I focus on targeted fixes rather than workarounds, keeping the codebase clean and maintainable. Deliverables will include: • Updated, compilable Android project • Clear commit messages or step-by-step notes for each change • APK or Play-ready bundle demonstrating sustained connectivity Once I review the codebase, I can give a precise timeline and cost. Initial debugging usually takes 1–3 days, depending on the root cause. Looking forward to reviewing the project and getting PLIGNET fully stable. Best regards, Maisam Raza Android Developer

I can help you diagnose and fix the VPN drop issue in your Android app, PLIGNET, so connections stay stable and users don’t lose internet unexpectedly. I’m very familiar with Android VPN APIs, background limits, and how OEM optimizations can interfere with long-running VPN services. I’ve previously stabilized VPN and networking apps that were being killed in the background, including handling Android 10+ restrictions, battery optimizations, and edge cases across different device manufacturers. This included improving service foreground handling, reconnect logic, and network change detection. My approach would be to reproduce the drop issue, review your existing VPNService implementation, logs, and connection flow, then refine the service lifecycle, keep-alive strategy, and error handling. I’d verify across multiple OS versions and common device brands. I would love to chat more about your project! Regards

Hi there, We understand your Android VPN app PLIGNET maintains UI connection status while the underlying WebSocket/VpnService session silently drops after 30–60 minutes, and you need root-cause tracing plus a reliable fix ensuring sustained tunnel stability under normal operating conditions. SEO Global Team has debugged Android VpnService implementations with okhttp-based WebSocket stacks, resolving foreground service lifecycle issues, Doze/App Standby interference, heartbeat misconfigurations, socket timeout policies, and backend idle disconnect thresholds through structured logging and long-duration stress testing. We will instrument the service and socket layers to capture lifecycle and heartbeat events, validate foreground-service persistence and power exemptions, implement resilient keep-alive and reconnect safeguards where required, and deliver a documented build proving stable 2+ hour continuous connectivity. Which Android SDK target and minimum versions are configured? Is the backend enforcing idle timeouts on WebSocket sessions? Does the app currently request battery optimization exemptions? Best regards, SEO Global Team

Hi, hope you are doing well. I would reproduce the drop with verbose logs, then instrument the VPN service and WebSocket layer to detect silent disconnects and force a clean reconnect or state update. On the socket side I’ll add proper ping or heartbeat intervals and tighten OkHttp timeouts, and on the Android side I’ll verify the foreground service setup, notification channel, wake locks if needed, and handling of network changes via ConnectivityManager so the tunnel doesn’t drift into a dead state. The UI will be wired to the real connection status, not a cached flag, so “connected” only shows when the tunnel is truly up. Deliverables are a compilable project with the fix, clear commit notes, and an APK or bundle that holds a stable connection through a two hour test with documented before and after behavior. I can start immediately; are you using OkHttp WebSocket, and do you already collect logs around the time of the drop, for example Logcat or backend disconnect events? Looking forward to your reply. Best.

Hi there, It sounds like PLIGNET’s VPN tunnel is dropping at the network layer while the UI remains stuck in a “connected” state, classic symptoms of a stalled WebSocket heartbeat, foreground-service timeout, or an aggressive Android power-management kill. I’ve spent the last 7 years diagnosing and fixing exactly these Android VpnService and WebSocket lifecycle issues, including keep‑alive tuning, foreground service stabilization, and power‑policy bypasses. I’ll trace the disconnect using log instrumentation, analyze your WebSocket heartbeat intervals, verify wake-lock and foreground-service persistence, adjust OkHttp/Netty timeouts, and patch any VPN service threading or binder-handoff flaws to ensure stable multi-hour sessions. Before I begin, can you confirm whether your current VPN service uses a dedicated wake-lock or relies solely on foreground service persistence? Best regards, Generoso III

Silent disconnects around the one hour mark usually mean Android battery optimization is silently killing your WebSocket keep alive pings or your foreground service is losing priority. I love fixing these sneaky background tasks. First I will run a trace on your VpnService and network traffic. I will send you a simple word document right away showing exactly where the connection drops so you know the exact scope. Then I will implement the fix to keep the heartbeat alive indefinitely. Since I can handle both the low level network debugging and the Android lifecycle rules you will not need to hire anyone else. Would you like me to review the source code right now so we can get this tunnel stable today?

Hi, I carefully reviewed your PLIGNET Android VPN issue where the UI stays connected but the underlying VPN and WebSocket session dies after 30 to 60 minutes. I’m confident I can trace the exact failure point and deliver a stable fix within 3 to 5 days, including a proven long run test. I’ve fixed similar Android VpnService and WebSocket keep alive problems before, including cases caused by power management, foreground service lifecycle, missing heartbeats, and silent socket stalls. I will add the right instrumentation to reproduce it, pinpoint whether it is service, network, or socket level, then implement a reliable reconnect or keep alive strategy and validate with a 2 hour plus continuous connection test. If you share how the tunnel is implemented and which WebSocket library you use, I can start right away. Looking forward to working with you, thank you!

Hey there, When the disconnect happens, do you see the VPN service still running in the background (foreground notification still active), or does the process get killed while the UI state stays “connected”? Cost: 700USD with a week| Recently I fixed an Android VpnService + WebSocket tunnel that died after ~30–60 minutes while the UI still showed connected - the root cause was a mix of missing heartbeats and aggressive power-management killing the networking stack, and I solved it by adding a reliable ping/pong keep-alive, proper foreground-service handling, and reconnection/state-sync logic. For this project, I will first reproduce the drop with logging, then trace VpnService lifecycle + WebSocket heartbeat and implement a durable keep-alive/reconnect fix so the tunnel stays up indefinitely under normal conditions. Just wondering, which WebSocket library are you using now (OkHttp / Netty / other), and are you using a foreground service with a persistent notification? Hope to discuss more on chat Best Nataliya
