Are your backend APIs failing with timeouts? In this video, I explain everything you must know about timeouts in backend systems — what they are, why they happen, how to configure them correctly, and how to debug them like a pro. We walk through: ✔ What is a timeout? ✔ Why backend systems have timeouts ✔ Types of timeouts (client, server, gateway, DB, network) ✔ Default timeout values in .NET / HttpClient ✔ How to configure and increase timeout in C# ✔ CancellationToken vs Timeout (real difference) ✔ Why browsers wait longer but HttpClient fails ✔ A complete live demo in .NET 8/9/10 ✔ Best practices to avoid cascading failures in microservices Timeouts are one of the most misunderstood backend failures — especially in distributed systems and microservice architectures. If you’re a backend developer, .NET developer, or working with APIs, you must understand how timeouts work to build reliable and scalable systems. 🔔 Subscribe for more backend + C# content!
