Connecting to a Snowflake Server With an Underscore in Server Name

Issue

Cannot connect to a Snowflake server with an underscore in the domain account's server name.

Environment

  • Tableau Desktop 2021.1.2
  • Windows 10
  • Snowflake

Cause

Connecting to a Snowflake server with an underscore in the domain account's server name is not allowed in Tableau. 

The issue is due to compliance with RFC 2396, which does not allow underscores in domain names. So, it is not a limitation with Tableau, but a limitation with java and the java libraries.
 
Snowflake is aware of these limitations and has resolved it by creating a dashed version of the URL as well. See this Snowflake documentation: Account Identifiers.
