Sharepoint Online Issues

Hi -,

I'm trying to use sharepoint online as a CMS with Framemaker 2020.

I can connect to sharepoint, create files and check them in

But when I go to check them out, they download locally, delete themselves and get the message that Framemaker cannot find the file.

The SP log has the below information...

Source        : System
Method        : DownloadFile
Date        : 15:39:41
Time        : 12/07/2022
Computer    : STKLOFC0388
Error        : The underlying connection was closed: An unexpected error occurred on a send.
Stack Trace    : at System.Net.WebClient.DownloadFile(Uri address, String fileName)
   at WindowsFormsApplication1.Utils.downloadFile(String url, String path)
   at WindowsFormsApplication1.SharePointOperstions.downloadSimpleFile(String path, String pathToDownload, String driveid, String siteid, String token, String siteweburl, String driveweburl)

Has anyone else had this issue and found a solution?
