### Bug Type (问题类型) server status (启动/运行异常) ### Before submit - [x] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - Server Version: Latest Code Build - Backend: Cassandra - OS: Ubuntu - Data Size: Just few `data` ### Expected & Actual behavior (期望与实际表现) I did following steps: 1. Started cassandra (V 5.0.3) 2. Started Hugegraph ``` ./start-hugegraph.sh Starting HugeGraphServer in daemon mode... Connecting to HugeGraphServer (http://127.0.0.1:8080/graphs)....OK Started [pid 1252693] ``` 3. Created one vertex from Swagger UI and its got created. 4. Stopped cassandra. 5. Again tried from Swagger UI and it's returning error: ``` Failed to fetch. Possible Reasons: CORS Network Failure URL scheme must be "http" or "https" for CORS request. ``` 6. Restarted cassandra and tried from Swagger but same issue ``` incubator-hugegraph-master/target/apache-hugegraph-incubating-1.5.0/apache-hugegraph-server-incubating-1.5.0/bin$ ./start-hugegraph.sh Starting HugeGraphServer in daemon mode...
