Bad Request issue
asp.net
Hello Everyone,I am facing a strange issue I have two deployments (A and B). Deployment B calls an API of Deployment A for package validation from inside an action filter. It works fine after deployment, but after running for some time (days), the call starts failing with 400 Bad Request, most likely before the controller is hit (possibly [ApiController] model validation or early pipeline). The request URL and parameters are correct, and the same call returns 200 when working. Doing an IIS reset immediately fixes the issue without any code or config changes. Has anyone experienced something similar with long-running apps, action filters doing external API calls, or IIS-related behavior?
