When you connect to a Snowflake database with the Snowflake data connector, the caslib initially connects but then reports that the CAS session has been disconnected. This applies in SAS^® Viya^® 3.4 and SAS Viya 3.5.

This issue occurs when you use a Snowflake ODBC driver version 2.20.5 or later. The Snowflake ODBC driver version 2.20.4 or earlier is unaffected.
