yes. You can simply replace the following code in DanbooruDownloader/Utilities/DanbooruUtility.cs

public static async Task<JObject[]> GetPosts(long startId, string username, string apikey)
        {
            using (HttpClient client = new HttpClient())
            {
                string url = GetPostsUrl(startId, username, apikey);
                string jsonString = await client.GetStringAsync(url);

                JArray jsonArray = JArray.Parse(jsonString);

                return jsonArray.Cast<JObject>().ToArray();
            }
        }

to

public static async Task<JObject[]> GetPosts(long startId, string username, string apikey)
        {
            string url = GetPostsUrl(startId, username, apikey);
            var target = new Uri(url);
            var handler = new ClearanceHandler
            {
                MaxTries = 3,
                ClearanceDelay = 3000
            };

            using (HttpClient client = new HttpClient(handler))
            {
                string jsonString = await client.GetStringAsync(target);

                JArray jsonArray = JArray.Parse(jsonString);

                return jsonArray.Cast<JObject>().ToArray();
            }
        }

and don't forget

using CloudflareSolverRe;

and if you are training deepdanbooru with https://github.com/KichangKim/DeepDanbooru
you will also encounter this issue.
for example,

> deepdanbooru download-tags [your_project_folder]

will also raise 403 error.
for python,you need https://github.com/VeNoMouS/cloudscraper

Thank you my knowledge of C is nonexistent but I was able to get it to work only issue now is its just non-stop

|ERROR|DanbooruDownloader.Commands.DumpCommand|Can't retryable exception was occured : Id=880

I don't know what when i should know if there a issue sense I have never used this application to know

[AXiX-official]

sorry,it's my fault.I missed another changing
in DanbooruDownloader/Commands/DumpCommands.cs
replace:

static async Task Download(string uri, string path)
        {
            using (HttpClient client = new HttpClient())
            {
                HttpResponseMessage response = await client.GetAsync(uri, HttpCompletionOption.ResponseHeadersRead);

                switch (response.StatusCode)
                {
                    case HttpStatusCode.Forbidden:
                    case HttpStatusCode.NotFound:
                        throw new NotRetryableException();
                }

                response.EnsureSuccessStatusCode();

                using (FileStream fileStream = File.Create(path))
                {
                    using (Stream httpStream = await response.Content.ReadAsStreamAsync())
                    {
                        httpStream.CopyTo(fileStream);
                        fileStream.Flush();
                    }
                }
            }
        }

with

static async Task Download(string uri, string path)
        {
            var handler = new ClearanceHandler
            {
                MaxTries = 3,
                ClearanceDelay = 3000
            };

            using (HttpClient client = new HttpClient(handler))
            {
                HttpResponseMessage response = await client.GetAsync(uri, HttpCompletionOption.ResponseHeadersRead);

                switch (response.StatusCode)
                {
                    case HttpStatusCode.Forbidden:
                    case HttpStatusCode.NotFound:
                        throw new NotRetryableException();
                }

                response.EnsureSuccessStatusCode();

                using (FileStream fileStream = File.Create(path))
                {
                    using (Stream httpStream = await response.Content.ReadAsStreamAsync())
                    {
                        httpStream.CopyTo(fileStream);
                        fileStream.Flush();
                    }
                }
            }
        }

also remember adding

using CloudflareSolverRe;

I greatly appreciate your response. However, my knowledge of C# is quite limited. I've tried to compile the existing code using my Visual Studio, but without any luck. I'm also stuck at the 403 step, just like you. Seeing your modifications has sparked my hope again, yet I've been unable to locate a compiled version in your fork, which leaves me unable to execute the code. Would you be able to provide an executable exe file that includes the fix for the 403 issue? I would be immensely grateful.
