使用RestSharp（在IIS中）时无响应结果

Question

This problem puzzle me so long time.

I write an asp.net project, and I use RestSharp to post my request to authorize whether user can log in the site.

Below is the code of the method of to call the authorize server

public static async Task<UserInfo> ValidatorResult(string userName, string passWord)
{
    var client = new RestClient(AuthUrl.BaseUrl);
    var request = new RestRequest(AuthUrl.LoginURL, Method.POST);
    //client.Proxy = new WebProxy("127.0.0.1", 8888);
    request.AddParameter(InformationDefine.CLIENT_ID_ID, InformationDefine.CLIENT_ID);
    request.AddParameter(InformationDefine.CLIENT_SECRET_ID, InformationDefine.CLIENT_SECRET);
    request.AddParameter(InformationDefine.GRANT_TYPE_ID, InformationDefine.GRANT_TYPE_PASSWORD);
    request.AddParameter(InformationDefine.MAIL_ID, userName);
    request.AddParameter(InformationDefine.PASSWORD_ID, passWord);
    var response = await client.ExecuteTaskAsync<UserInfo>(request);
    return response?.Data;
}

And this is the address const of my authorize server:

class AuthUrl
{
    public const string BaseUrl = @"https://account.mysit.com.cn";

    public const string LoginURL = @"/api/oauth/access";
}

When I use these codes in my local environment, I can get the right UserInfo, but when I publish this project to IIS server, I always get 500 code when I call this method.

The error is "response?.Data" is null.

I want to solve this problem and I tried so many ways.But all failed.

I want get the reason in the IIS so I added one line code

client.Proxy = new WebProxy("127.0.0.1", 8888);

It's so amazing that when I open the fiddler, sometimes I can get the UserInfo, but when I close fiddler, the error appeared again.

Can you tell me why?

And How to solve this problem.

Thank you.

Ps I forgot one detail, in the IIS the binding domain of mysite is not below kinds "localhost" or "ip:port".

I have an another domain like "hai.xxxxx.co", the address of my site is "hai.xxxxx.co:8088".

Update my the binding config in iis

I think I know the key of this problem.

Because the authorize is not from my service, so I need a reverse proxy.

It's the reason of when I open the fiddle and set proxy in the code, I can't get response normally.
