雪花jdbc驱动程序抛出net.snowflake.client.jdbc.SnowflakeSQLException：jwt令牌无效

我通过遵循this生成了RSA密钥对，并且还使用以下代码片段连接了Snowflake。
内部生成的JWT令牌似乎确实基于jwt.io有效，但是在建立连接时，客户端抛出以下错误：

net.snowflake.client.jdbc.SnowflakeSQLException: JWT token is invalid.

什么可能导致Snowflake服务器返回错误？

解决方案

原来设置账户时，不能包含地域段。
假设全帐户名为"；xy12345.us-East-1-gov.aws"；，则必须按如下方式设置帐户属性。

ds.setAccount("xy12345")
