Can not install adobe CC software from adobe create cloud

I had created adobe update internal server and config file (AdobeUpdater.Overrides) with adobeupdateserversetuptool and Apache, and deploy this file to client PC, Client PC had installed adobe create cloud 4.8.1.435, but when i want to install adobe app in adobe create cloud,it show below error

Exit Code: 125

-------------------------------------- Summary --------------------------------------

- 2 fatal error(s), 0 error(s), 0 warnings(s)

FATAL: Fatal Error '125' occurred while download

FATAL: Error occurred in install product workflow with error code 125 error message {http://CN-GZ-SRV-AUS//ACC/services/ffc/packages//PHSP/20.0.4/win64/Application.json?name=PHSP&version=20.0.4&platform=win64&build=20.0.4.76,P:-4,PS:404,G:-4}

I found Application.json.aamdownload in adobe update internal server floder (ACC/services/ffc/packages//PHSP/20.0.4/win64/) is 0 KB,is that right?

Create AdobeUpdater.Overrides command below

AdobeUpdateServerSetupTool --root="F:/AdobeUpdate" --genclientconf="F:/AdobeUpdate/config/AdobeUpdaterClient" --url="http://CN-GZ-SRV-AUS/"

Client PC can use browser to accecc http://CN-GZ-SRV-AUS/ and download files without any error.

How can I slove this issue?

Thx
