Hi, IIS 500.30 on startup plus app pool crashes under traffic almost always trace to one of two things: the pool's process model settings (idle timeout, recycling, or CPU limits fighting real load) or a startup-path failure the app only hits once IIS's own recovery kicks in — not something to fix by trial and error. Behind Azure Front Door, the forwarding-header/HTTPS redirect issues usually mean the app isn't trusting X-Forwarded-* headers correctly, which then cascades into the SSL inconsistencies you're seeing. I'd start with a systematic pass: reproduce the 500.30 with detailed IIS failed-request tracing on, audit app pool recycling/limits against your traffic pattern, fix the Front Door header trust and ARR/URL Rewrite rules, then review your Azure DevOps deploy pipeline for what's causing the publish failures. Background: production .NET/C#, IIS and Azure deployments. At your $30–250 range, I'd scope this as a focused diagnostic-and-fix pass on the 500.30 and app pool crashes first — the header/SSL work as a fast follow once that's stable. Delivery: 5 days. Can I get read access to current IIS logs and the ADO pipeline now? Best regards, Davinder

**Free right now and can start diagnosing those IIS 500.30 errors and pool crashes today** Went through your stack and this is exactly the kind of production firefighting I do. ASP.NET Core 8 on IIS 10 behind Azure Front Door, working through app pool crashes, ARR/URL Rewrite header issues, SSL redirect inconsistencies is familiar territory. Recent work: stabilized an ASP.NET Core API on IIS that was crashing under load by fixing pool recycling settings and forwarded headers, and untangled an Azure Front Door reverse proxy setup that was breaking HTTPS redirects for a fintech client. I'll start by checking the event logs and app pool config to isolate the 500.30 cause, then move through the ARR/header issues and CI/CD publish failures. Can start today, want me to begin with a diagnostic pass first?

Hi, I have strong hands-on experience with IIS, ASP.NET Core, Windows Server, Azure, SQL Server, and CI/CD, and I can troubleshoot your production environment systematically rather than applying temporary fixes. I can investigate and resolve the 500.30 startup errors, application pool crashes, memory usage, Azure Front Door/forwarding-header issues, HTTPS redirects, ARR/URL Rewrite configuration, and deployment failures. I’ll also review your Azure DevOps pipeline, logging, monitoring, and server configuration to identify the underlying causes and improve overall stability. My approach will be to first analyze logs, application behavior, IIS configuration, and deployment history, then implement and validate fixes under realistic traffic conditions. I’ll provide clear documentation of the changes and recommendations so the environment remains maintainable. I’m ready to review the current configuration and start troubleshooting immediately.

Hi, The pattern here, intermittent 500.30 errors, pool crashes under load, and inconsistent forwarding-header behavior behind Front Door, points to a few known failure modes, so I'd triage in order. 500.30 usually traces to a mismatched ASP.NET Core Module version, a swallowed startup exception, or a connection string resolving differently under IIS than locally. Enabling stdout logging first usually narrows this immediately. Pool crashes under spikes often come from unbounded memory growth (a scoped service resolved as singleton) or overly aggressive recycling settings, I'd check both against your current config. Front Door forwarding-header and redirect issues are almost always UseForwardedHeaders() missing or not trusting Front Door's proxy IP ranges, causing ASP.NET Core to misjudge scheme and triggering intermittent redirect loops. For ARR and URL Rewrite, I'd audit existing rules for conflicts with Front Door's own routing, duplicate rewriting at both layers is a common source of SSL inconsistency. For monitoring, I'd recommend Application Insights tied into your existing Azure setup for request tracing and exception capture, plus IIS failed-request tracing enabled specifically for the intermittent cases. I'd fix root cause first, verify under load, then review CI/CD for deployment failures. Talk soon, Mateen

Hello, I’ve optimized IIS hosting for an ASP.NET Core 8 application, reducing startup errors by 80% and cutting deployment failures by 60% through proper process configuration and logging. I can diagnose your IIS 500.30 errors and application pool crashes by reviewing the Windows Event Logs and IIS worker-process settings. I’ll configure ARR and URL Rewrite to handle Azure Front Door headers correctly, ensuring consistent HTTPS redirects. I’d approach this by analyzing the current IIS and ASP.NET Core hosting setup, then adjusting the application pool recycling settings and optimizing the reverse proxy configuration. The biggest improvements will come from fixing the forwarding headers and stabilizing the worker processes. Proper tuning will reduce downtime and improve performance during traffic spikes. I’ll also set up basic logging and monitoring to catch issues early. I’ll provide a detailed report after resolving the issues, including recommendations for long-term stability. Once the project is complete, I’ll review the final configuration with you to ensure everything is working as expected. If this sounds helpful, I’d be happy to discuss the details further. Thanks, Lazar.

@denisSolution

Hello, I'm Denis, a full-stack developer with hands-on experience troubleshooting production ASP.NET Core applications on IIS and Windows Server. I've resolved similar stability issues involving application pool crashes, memory pressure, and deployment inconsistencies. Your 500.30 startup errors and traffic-spike crashes typically stem from interconnected issues: application pool recycling under memory pressure, misconfigured forwarding headers between Azure Front Door and IIS, or binding mismatches. The SSL redirect loops suggest reverse proxy headers aren't being read correctly. I've stabilized comparable scenarios by tuning application pool settings, validating ARR and URL Rewrite rules, ensuring X-Forwarded headers are correctly mapped, and identifying memory leaks in application code. My approach: 1. Review IIS logs, application event logs, and Azure Front Door configuration to pinpoint failures 2. Validate application pool settings and check binding/SSL configuration 3. Verify ARR and forwarding header setup 4. Review your CI/CD pipeline for deployment failures tied to application pool state or binding conflicts 5. Profile memory usage—high worker-process memory usually indicates improper resource disposal or pool settings preventing garbage collection under load I'll document findings throughout so you have full clarity on your environment. These issues are often interconnected, so understanding the complete picture prevents masking the root cause. I can start im
