Hi, 

Been doing some training in NLX with SF as a datasource for my models. After about 30 minutes, the connection to SF fails and I get the error below. Losing hours of work. Any help appreciated.

The following errors occurred:

1. Error retrieving metadata for model(s) associated with data source 'Salesforcev3'. Please check models' properties to ensure they are set correctly. Unable to authenticate to Salesforce. Metadata could not be retrieved. Login has been cancelled
