When you try to preview any published document from Vibe, a new windows open but stays empty. In the appserver.log file you see a conversion in HTML format has timed out, like in example bellow:
2020-09-15 09:22:40,848 ERROR [pool-misc-thread-1] [com.novell.teaming.docconverter.kv.TextKeyViewConverter] - Text conversion timed out for test20200915.docx (ifp=D:\Novell\Teaming\cachefilestore\kablink\22\22543\folderEntry_158175\402885db74909cf0017490a054610004\text\s160015426067014899470591909675103.docx, ofp=D:\Novell\Teaming\cachefilestore\kablink\22\22543\folderEntry_158175\402885db74909cf0017490a054610004\text\t160015426067017849041412405370498.txt, timeout=300000) (pagerId=1, status=3, Exception=null,
Viewing the same document on Linux based Vibe works just fine.
This seems to be related more often specifically on Windows platforms. The KeyView parts involved in a HTML conversion of a document are not loaded. Vibe then times out waiting for the KeyView process.
In many case, installing older version of Microsoft Visual C++ 2010 x64 Redistributable application fixed this problem.
You will need to restart Vibe service afterwards.
It might be also necessary to re-index older, already published documents just in case you are still unable to preview them.
