OnlyOffice - incorrect path

I using OnlyOffice Document Server v 7.4.1-36 on Windows. I have problem with incorrec path to scripts. When i run doceditor in javascript console log i get error WebSocket connection to 'ws://localhost:1725/7.4.1-36/doc/Khirz6zTPdfd7/c/?EIO=4&transport=websocket' failed: 

 http://localhost:1725/7.4.1-36/doc/Khirz6zTPdfd7/c/?EIO=4&transport=polling&t=OhVSsyb 502 (Bad Gateway)

But my correct path is http://localhost:1725 without 7.4.1-36 . Where is the problem?
In my folder i dont’ have folder 7.4.1-36 .
