Size limit? (bug)

[untuned]

I've noticed that somewhat large files error out with a 400 bad request error.

Message:
The remote server returned an error: (400) Bad Request.

Request URL:
https://XXXXXXXXX/upload

Response:
{"message":"Token not specified."}

Stack trace:
   at System.Net.HttpWebRequest.GetResponse()
   at ShareX.UploadersLib.Uploader.SendRequestFile(String url, Stream data, String fileName, String fileFormName, Dictionary`2 args, NameValueCollection headers, CookieCollection cookies, ResponseType responseType, HttpMethod method, String contentType, String metadata)

The only problem is that the token is specified.

The maximum file size upload is determinated by the post_max_size and upload_max_filesize your in php.ini settings (You can see those logging in into the admin account > System).
Example:

Which version of xbackbone?
How are set those php.ini in your settings?
How much do you mean with "large file"?
