I am receiving an error every night specifically at 8pm and the transfer fails, transfer is successful every other hour of the day, The transfer failed: 'Timeout taking VSS snapshot of XXX'

I have this server setup to backup every hour and is successful every time but failed every single day only at 8pm, The transfer failed: 'Timeout taking VSS snapshot of xxx', Read on another post about sql but this sever isnt set up that way, and after checking event logs i do not see any errors or anything of significance at around that time. I do have the stack trace for this issue.
