Network connection was lost for InDesign CC 2015

[s_dinil]

Getting the error as below;

Checked all the network drives and it is all working. Other programs are also working from the network, so it is nothing from the network. Has been happening for InDesign File only. Using CC 2015 version of InDesign.

Checked the forum - Indesign "network connection lost"  - It is still Unanswered. Do we have a solution for it?

It may have been interrupted. Those problems have been reduced with InDesign CC 2017. Why do you not upgrade?

I'm having a similar problem - with CC 2017. "The network connection was lost for the file ***, or the file was modified by another process."

Then it shuts down. When I re-open, everything is fine. I'm working on a file on my computer in my home - not on any network.

Thoughts??
