Hi,
This issue is not related to Snowflake key-pair authentication being restricted in Free Cloud. Mendix Free (Sandbox) environments do not block Snowflake key-based authentication specifically.
The real limitation is different.
Mendix Free Cloud environments have network restrictions:
If you are trying to:
It will likely fail in Free Cloud due to platform network and runtime limitations.
This is unrelated to paid vs free in terms of Snowflake authentication type.
Free Cloud (Sandbox):
This is documented platform behavior.
Snowflake integration works when:
If you need Snowflake integration:
The issue is not about Snowflake key-pair authentication being limited to paid versions.
The limitation is that Mendix Free Cloud does not support external database connectivity reliably.
To use Snowflake from Mendix runtime, you need a licensed environment or Private Cloud deployment.
Hi Ayman Ahmed
Yes in Mendix Free Cloud, Snowflake key‑pair authentication generally does not work. Free Cloud has strict outbound‑connection and certificate restrictions, and it does not allow custom certificates, private‑key–based authentication, or IP‑whitelisting, all of which Snowflake requires for key‑pair auth. Because of this, Snowflake connections only work reliably in licensed (paid) Mendix Cloud nodes, where you can configure environment variables, private keys, static IPs, and secure outbound traffic.
I hope this helps
