Hello @wangzhen

OS: windows 10

First things first, please note that Document server doesn’t support Windows 10 (any desktop versions of Windows). Please check out this title: ONLYOFFICE Docs for Windows system requirements - ONLYOFFICE

Please try deploying Document Server on the Windows server and re-check the situation.

Hello @rahul123mer
Sorry for the late reply.
Please reproduce the situation and make screenshot of the error itself in the web browser (with opened browser console > Console and Network tabs). After that please provide us with whole Document server logs folder. It’s located here: Program Files (x86)\Ascensio System SIA\DocumentServer\Log
