Make sure you're not running any jobs (My Jobs | Current Jobs), and let's stop vRanger's services under Services.msc.
You can stop them from top to bottom.
Using File Explorer, go to vRanger's installation folder, the default path is "C:\Program Files\Quest\vRanger". Make sure you View the File Extensions.
Find the file "Vizioncore.vRanger.Service.exe.config", copy and paste it to make a copy as a backup.
Edit the file with Wordpad or Notepad (You might need to run as administrator).
Find this Key:
<!-- Sets the amount of time, in hours, before the system will abort the repository replication job --> <add key="RepositoryReplicationSanityTimeout" value="24"/>
You can increase the Value from 24 to a preferred one.
Save the File and you can start vRanger's services from bottom to top.
