Connection to a Network Document is lost after computer resumes from standby

Office 2019 on Windows 10 build 1809 seems to be losing connection to Network Drive documents. I am having an issue where if a network document is left open and a user walks away. When they return and unlock their computer Office only gives them the option to Save As. It seems that Office is losing the connection to the network drive where the document is stored. I found a similar article for Office 2007 & 2010. Not sure if the same fix can be applied.
