In the event log you can encounter the following message:

A timeout was reached (30000 milliseconds) while waiting for the SQL Server Reporting Services (InstanceName) service to connect.

Or in the system – event viewer log:

Timeout (30000 milliseconds) waiting for the SQL Server Integration Services service to connect.

Solution:

Enter regedit.
in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

• Modify the key ServicesPipeTimeout if it exists, and change the actual value to 120000 (keep in mind you must enter a decimal value)
  
• If the key does not exist, you can create it: ServicesPipeTimeout (type : DWORD / decimal) value: 120000. The value is in milliseconds (120000 = 120s = 2mn)
• Reboot the computer
