asp.net core 上传文件服务器拒绝是为啥？

Posted 2023-03-14

上传文件仅有几M~无论用常规form提交还是XMLHTTPREQUEST提交都会出现，几百K文件很少出现，几M基本就无法成功，最近才将项目移植到asp.net core 3.0~有大神帮忙解答么。
前端异常：net::ERR_CONNECTION_RESET或net::ERR_CONNECTION_ABORTED
服务端异常：
Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer: Error: Connection ID "18374686511347007599", Request ID "80000070-0007-ff00-b63f-84710c7967bb": An unhandled exception was thrown by the application.
