Background

When sending a document from NetDocuments to SignatureBridge, this error is shown:

This can be caused by having restricted IP addresses. 

Resolution

If your site has configured IP Address Restrictions, you'll need to add the SignatureBridge IP address to the list of allowed IP addresses.  To do so:

• Log into NetDocuments as a user with Admin Credentials
• Select "Users and Groups"
• Choose "Configure advanced authentication options"
• In the "Requirement Type" choose the IP Address
• Add in the IP address for SignatureBridge.
