上传文件遇到"连接被对方重设"异常

[yhcc]

感谢你开源了这个云盘，非常简洁。部署完成之后，我通过admin用户登录，尝试上传文件时，遇到了以下的报错，

TYPE:
Exception
CONTENT:
org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: 连接被对方重设

        at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:877)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:661)
......

这种问题应该怎么解决呢？
PS: 我是通过mac上传的，不管chrome还是safari浏览器都会报这个错误。

前端会显示
提示：出现意外错误，文件：[readme.txt]上传失败，上传被中断。
