【问题描述】：
我正在做一个项目，使用 Windows 中的 JDBC 连接到在 Linux 上运行的 TDengine 数据库。
配置如下：
spring.datasource.driver-class-name=com.taosdata.jdbc.TSDBDriver
spring.datasource.url=jdbc:TAOS://192.168.2.58:6030/test?timezone=UTC-8&charset=UTF-8&locale=en_US.UTF-8
spring.datasource.username=root
spring.datasource.password=taosdata
我也调查了TDengine的日志。

我不知道发生了什么。有人可以提示如何解决它吗？
