Snowflake Authentication failure in Development environments if the Account name has an '_'

We have deployed a fix for the Snowflake issue that was causing authentication issue affecting accounts with underscores in the account identifier. Rollout is now complete across production tenants.

We are monitoring to confirm error rates remain at baseline. Please reach out to support@getdbt.com if you have any further questions.

We are currently investigating an issue affecting Snowflake connections in dbt Cloud Development environments. Users attempting to set up new Snowflake connections with account identifiers containing underscores experience authorization failures.
Existing sessions are not impacted, this only impacts new users re-authenticating to snowflake in the developer credentials.
Workaround: Replace underscores with hyphens in the Snowflake Account field in your dbt Cloud connection settings (for example, my_account → my-account) and avoid using dynamic configuration containing {{env_var()}} config in the hostname field.
