There was an unexpected error (type=Internal Server Error, status=500).

回答: "There was an unexpected error (type=Internal Server Error, status=500)"是一个常见的错误信息，通常表示服务器在处理请求时发生了内部错误。根据引用\[1\]中提到的博客，这个错误可能与使用Thymeleaf模板引擎有关。在解决这个问题之前，你可以先检查一下你的Thymeleaf语法是否正确，并确保你已经添加了正确的Thymeleaf依赖\[3\]。如果问题仍然存在，你可以尝试参考引用\[1\]中提到的第二篇博客，该博客提供了一些关于解决Thymeleaf相关问题的方法。另外，引用\[2\]中提到的错误信息"mysql.cj.exceptions.CJException: null, message from server: 'Host 'x' is not allowed to connect'"可能也与你的问题有关，你可以检查一下你的数据库连接配置是否正确。希望这些信息对你有帮助。
