c# - Why am I not getting anything from my webrequest? What am I supposed to look for?

Question

First of all I am new to C#. I am writing a WPF program in Visual Studio 2019. In my project I have multiple web requests and whilst testing how they work the functionality was minimal: only the web requests were made and they were working fine until now. The login authorization request still works.

This is my webrequest.

using (var client = new WebClientEx())
{
    client.BaseAddress = serverurl.serviceurl;
    client.UseDefaultCredentials = true;

    string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(excelvertibas.username + ":" + excelvertibas.password));
    
    client.Headers[HttpRequestHeader.Authorization] = "Basic " + credentials;

    ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
    client.Timeout = 90000;
                    
    byte[] postArray = Encoding.ASCII.GetBytes(JsonConvert.SerializeObject(domObjectVariables));
    client.Headers.Add("Content-Type", "application/json");//----------------
    client.Encoding = Encoding.UTF8;
    byte[] responseArray = client.UploadData(serverurl.serviceurl + "StartAddDigitalObject", "post", Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(domObjectVariables)));  //----------------------------
    domMetadataAddResponse = JsonConvert.DeserializeObject<StartAddDigitalObjectResponse>(Encoding.UTF8.GetString(responseArray));
}

The base address works, I tested it manually through Postman.

Username and password are also correct which I have tested.

Post array is also passing information which is needed, and I have checked it whilst adding breakpoints.

My question is why could this be not working anymore and what should I look for?

fyi this is the line of code where is should be getting information back into the response array but for some reason it stays null.

byte[] responseArray = client.UploadData(serverurl.serviceurl + "StartAddDigitalObject", "post", Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(domObjectVariables)));  

After this the program breaks because the response array contains nothing when I try to pass it further.
