Could you please provide Minimal, Reproducible Example? It will be much easier to advice if we can test exact application. The good practice is to containerize such example.

Thank you for replying. I can't. It's company source code

I am not asking for sharing your proprietary code. What you should do is to create test application, without any internal stuff which can be shared with us. It should just mimic the problematic behavior.

@Jane-Okuma just in case checking, is it an old APS.NET or ASP.NET Core hosted on .NET Framework 4.8?
