We have detected Snowflake driver versions 3.13.x are having a problem properly initializing SSL handshake.
The error message in the JCo log reflecting this is:
net.snowflake.client.jdbc.SnowflakeSQLException: JDBC driver encountered communication error. Message: Exception encountered for HTTP request: Unsupported or unrecognized SSL message.
To avoid this issue, please use tested lower version of the driver: snow-jdbc-3.12.9.jar.
