When using Key Pair authentication and creating a new Snowflake connection, you might encounter the following error:

Illegal Argument

Resolution

The provided private key file (.p8) is not in the correct format, or the key file password is invalid.

To get the actual error, install SnowSQL utility in the Linux machine where the Qlik Data Movement gateway is installed and try to connect to the same account:

snowsql -a <account> -u <username> --private-key-path <path to file/rsa_key.p8>

This will provide the exact error on why the connectivity is failing and assist in identifying which root cause applies.
