ServicePointManager.FindServicePoint blocks

I am calling this method:

ServicePoint sp = ServicePointManager.FindServicePoint(mRequest.RequestUri, this.MapDataWebProxy);

for getting a service point, but when there is no internet conection available, the method just doesnt return.

Any ideas on how I can prevent this or set a timeout?

You can try to verify Internet connection before calling that method. It can be done something like this: 

[DllImport("wininet.dll")]
    private extern static bool InternetGetConnectedState(out int Description, int ReservedValue);

    //Creating a function that uses the API function...
    public static bool IsConnectedToInternet()
    {
        int Desc;
        return InternetGetConnectedState(out Desc, 0);
    }

    public ServicePoint GetServicePoint()
    {
        if (!IsConnectedToInternet())
        {
            return null;
        }
        return ServicePointManager.FindServicePoint(mRequest.RequestUri, this.MapDataWebProxy);
    }

Also Internet can be checked in another way. Without using of "wininet.dll" library: What is the best way to check for Internet connectivity using .NET?
