<!-- Answer --> 连接 Hubble 到 PD 时出现错误的常见原因可能包括以下几点： 1. **版本不匹配**：确保 hugegraph-client 和 hugegraph-server 的版本匹配 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 2. **服务不可用**：检查 PD 服务是否在指定的主机和端口上可用 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 3. **主机名或 IP 问题**：确认主机名或 IP 地址可以解析，并且是授权的 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 4. **端口问题**：确保使用的端口在允许的范围内，并且是授权的 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 5. **用户名或密码错误**：如果服务器启用了访问控制，请确保提供正确的用户名和密码 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 6. **连接名称或图名称不匹配**：确保连接名称和图名称符合正则表达式要求 <sup>[[1]](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties)</sup>. 根据架构模式，确实应该连接到 PD。请检查以上几点，并确保 PD 的默认端口（gRPC 端口 8686，REST 服务端口 8620，Raft 服务地址端口 8610）没有被防火墙或其他网络设置阻止 <sup>[[2]](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-pd/hg-pd-dist/src/assembly/static/conf/application.yml)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* GitHub link: https://github.com/apache/incubator-hugegraph/discussions/2694#discussioncomment-11237356 ---- This is an automatically sent email for dev@hugegraph.apache.org.
