Cookie issues while opening any webpage from project

Question

Hello, I'm currently having issues with the below two exceptions when refreshing any webpage in the project after a random number of times. My current theory is that after passing the context for APIHelper, it becomes null for whatever reason or at least the cookie array becomes empty or null. I can't really tell much with the Error Trace as it only mentions a cookie issue and not where the attempted accessing is being made. Any help would be greatly appreciated.

Using:

.NETFramework v4.8

ASP.NET MVC 5.3

public GestionController()
{
    model = new GestionModel();
    api = new APIHelper(System.Web.HttpContext.Current);
    api.VerifyCredentials();
    
    Debug.WriteLine("GestionController created");
}

///APIHelper.cs
public bool VerifyCredentials()
{
    HttpCookie currentUnitBuiness= context.Request.Cookies["CurrentUnit"];
    string gestionName = context.Request.RequestContext.RouteData.Values["subdomain"].ToString();
	if( gestionName != currentUnitBuiness.Value)
	{
		//...SQL management...
	}
}

Exceptions:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

It looks like you are using the old unmaintained browser capabilities object, and it getting an error on parsing the request data.
