我在尝试访问拉取任务队列时遇到此错误。直到上个星期五（10月5日），它才能完美运作。今天（10月8日）它没有用。
我从Websphere Application Server v7运行它，下面是2个导入的证书：accounts.googleapis.com:443和www.googleapis.com:443。
我正在使用Task Queue API下面的这个版本：
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-taskqueue</artifactId>
<version>**v1beta1-1.2.0-beta**</version>
</dependency>
你能帮我吗？

您使用什么凭据？如果它是OAuth令牌，令牌是否可能已过期？
