Salesforce is disabling TLS 1.0 encryption protocol on March 4, 2017. Any inbound and outbound connections will need to use the TLS 1.1 or TLS 1.2 encryption protocol.

For old versions of Omniscope, Salesforce Input and Output blocks may show the following warning message:

Salesforce API error
TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.

In order to comply with this update, Omniscope has to be updated to the latest version available (b1835) from the downloads page.

For more information, please visit Salesforce Update Documentation.
