Did you change anything on the server side before this issue occurred? Please make a screenshot of an error and provide us with Document server logs folder.
Hello, it works now with the new version of the connector (2.1), just have to wait a few minutes after document has been closed from OnlyOffice, because while keeping document open in OO, SharePoint doesn’t see the modifications (despite the OO autosave saying it’s saved correctly)
Hello @infobc
This is expected behaviour. Document server won’t send a new version of the file to the storage while editing session (editor tab\frame) is open. I assume that you see ‘All changes saved’ on the bottom line of editor while you are editing a file. This message means that new changes are collected to Document server database and cache. But the final version of the file will be built when editing session is over.
You can check how it works here:ONLYOFFICE Api Documentation - How It Works
By the way. I believe that ‘a few minutes’ for building and sending a new version of a file to storage is a little bit long. Please recheck the situation and provide us with details and test file.
