NSIS 下载超时

NSIS Downloading timeout

我已经构建了一个 NSIS,它已经运行了几个月, 突然出现了 JRE 下载失败的问题,我已经测试了下载 link 是好的,如果有人可以帮助部分代码如下,请提出可能的解决方案:

!define JRE_URL "javadl.sun.com/webapps/download/AutoDL?BundleId=69476"
Function GetJRE
    MessageBox MB_OK "${PRODUCT_NAME} uses Java ${JRE_VERSION}, it will now \
                     be downloaded and installed"

    StrCpy  "$TEMP\Java Runtime Environment.exe"
    nsisdl::download /TIMEOUT=30000 ${JRE_URL} 
    Pop $R0 ;Get the return value
            StrCmp $R0 "success" +3
            MessageBox MB_OK "Download failed: $R0"
            Quit
    ExecWait 
    Delete 
FunctionEnd


Function DetectJRE

Push [=11=]
Push 

; for 64-bit registry
SetRegView 64
ReadRegStr  HKLM "SOFTWARE\JavaSoft\Java Runtime Environment" "CurrentVersion"
;MessageBox MB_OK "JRE CurrentVersion "
;StrCmp  ${JRE_VERSION} Done

StrCpy [=11=]  1 0
StrCpy   1 2
StrCpy  "[=11=]"
;MessageBox MB_OK "JR CurrentVersion $JR_VERSION"
;MessageBox MB_OK "JR CurrentVersion "
IntCmp 16  Done JavaVerNotCorrect JavaVerNotCorrect # if not JRE 1.6,download from the web


JavaVerNotCorrect:
Call GetJRE

Done:
      Pop 
      Pop [=11=]
FunctionEnd

nsisDl 使用自定义 HTTP 库。请改用 INetC,它使用与 Internet Explorer 相同的 HTTP 库。
