The same file can be played on two servers, but starts with the error ’ there was a problem playing this item ’ on the third server. What could be the problem?

disk space for transcoder temp directory?
Plex is installed on Windows 10. The temp folder is not specified. You must specify?
Sorry for machine translation text
If you do not set the transcoder temp directory, it should default to
C:\Users\xxxxx\AppData\Local\Temp\
Best really is to enable debug logging on the server
restart the server
try and get the error
and then take a screenshot (showing url and time when the error was returned)
and locate the Plex Media Server.log
and attach here with the screenshot

If there is a disk space issue it would show in the log
Thank you Very Much. The thing really was to specify the temp folder.
