* **Reason:**: NC was offline due to maintenance for a moment. There is error in OO log with ECONNREFUSED to NC URL.
Due to the operational characteristic, ONLYOFFICE Docs saves a document only after the document has been closed by all the users who edited it. To avoid data loss, you must forcefully disconnect the ONLYOFFICE Docs users when you need to stop ONLYOFFICE Docs in case of the application update. 
* **Fix:** Always gracefully shutdown OO before touching NC application using ''documentserver-prepare4shutdown.sh'' script.
