Users get "Your Conga Session has Expired" immediately upon starting Conga Composer.
This error occurs immediately upon starting Conga Composer and it's caused by the "Lock IP Address" setting being enabled.
What to do
Disable the "Lock IP Address" setting for hosted AppExchange applications.
- Navigate to Salesforce Setup > Administration Setup > Security Controls > Session Settings.
- Ensure that the "Lock sessions to the IP address from which they originated" field is not checked.
You must RESTART all instances of the browser for the setting to take effect.
