Synchronisation failed due to open file which are in fact not open

[MarcelMe]

I was working on one station in Indesign saved in to Creative cloud. A little later my system crashed (due to other progamm). When I switched over to another station Creative Cloud came with a message that synchronisation failed as files in a folder are still open. 
So I went back to other station opened and closed InDesingn file. Back again the second station Creative Cloud still will not sync files.

How to solve this issue?

restart the problematic computer or terminate the hanging process.

Thanks for the quick reply. Restarting both stations did solve the issue.
