Please move this to BasicMiddleware. What settings do you have for ForwardedHeaderOptions?

IS same for all 3 configuration

var forwardedOptions = new ForwardedHeadersOptions
            {
                RequireHeaderSymmetry = false,
                ForwardedHeaders = ForwardedHeaders.All,
                KnownNetworks =
                {
                    new IPNetwork(IPAddress.Parse("103.21.244.0"), 22),

@jkljajic were you able to figure out what the issue was?

[jkljajic]

@muratg sorry i just give up and use X-Real-IP from Nginx and do not use internal get IP method
