Firebase突然报告无效签名 [英] Firebase suddenly reports invalid signature

问题描述

我们目前正在托管一个Java / Spring服务器，包括 SAP Cloud Platforms （Hana Cloud）。身份验证在过去的几个月里运行良好，但昨天突然停止工作，然后在约30分钟后恢复，今天又突然停止工作了。错误总是：

We are current hosting a Java/Spring server including firebase ID token verification on SAP Cloud Platforms (Hana Cloud). The authentication worked fine for the last few month, but suddenly stopped working yesterday, then it recovered after ~30 minutes and today it suddenly stopped working again. The error always is:

java.util.concurrent.ExecutionException：
com.google.firebase.auth.FirebaseAuthException：Firebase ID令牌有
无效签名。请参阅
https://firebase.google.com/docs / auth / admin / verify-id-tokens for
有关如何检索ID令牌的详细信息。

java.util.concurrent.ExecutionException: com.google.firebase.auth.FirebaseAuthException: Firebase ID token has invalid signature. See https://firebase.google.com/docs/auth/admin/verify-id-tokens for details on how to retrieve an ID token.

我在本地测试它仍然工作正常。什么可能以这种不可预测的方式导致这个错误？ firebase-backend是否有关于Id令牌验证请求的请求限制（这仍然很奇怪，因为其他时候它在重载下运行得很好）？

It is still working fine when i test it locally. What could cause this error in this unpredictable way? Are there request limits on the firebase-backend regarding Id token verification requests (which would still be strange, because other times it worked under heavy load just fine)?

任何可能导致此问题的想法？我找不到任何有关此错误的信息。
谢谢！

Any ideas what might be causing this? I could not find really anything regarding this error. Thanks!

推荐答案

根证书确实存在服务器配置问题。遗憾的是，我无法提供任何细节，因为我没有直接访问服务器，只有系统管理员给我的信息。

It appears that there indeed was a server configuration problem with the root certificate. Sadly i cannot give any specifics, because i don't have direct access to the server and only the information the system admin gave me.
