How to implement solution with asynchronous http client in c# 10 - unexpected timeout errors
I'm trying to implement I've been working with an scenario with the `HttpClient` class in C# 10 while trying to implement an asynchronous method that fetches data from an external API..... Despite setting a reasonable timeout, I keep getting a timeout exception intermittently. Here’s the method I have: ```csharp public async Task<string> FetchDataAsync(string url) { using (var httpClient = new HttpClient()) { httpClient.Timeout = TimeSpan.FromSeconds(5); var response = await httpClient.GetAsync(url); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } ``` I've tried increasing the timeout to 10 seconds, but the scenario continues. The exception I receive is: ``` System.Threading.Tasks.TaskCanceledException: The operation has timed out. ``` I also verified that the URL is correct and reachable. To troubleshoot, I added logging before and after the `GetAsync` call, and it shows that sometimes it takes longer than expected to reach the external server. I read that the scenario could be related to DNS resolution or network conditions, but I'm unsure how to properly handle this situation. Additionally, I’ve noted that the application runs behind a corporate proxy which may affect connectivity. Would wrapping the HTTP client in a retry policy using Polly help, or are there other best practices I should consider to mitigate these timeout issues? Any guidance would be appreciated! My development environment is Ubuntu. I'm on macOS using the latest version of C#. How would you solve this? I'm working in a macOS environment. Has anyone else encountered this?
