Why Cannot I Access the Obtained Inference Request Address from the Initiator Client?

Symptom

After a real-time service is deployed, you can obtain the address of the called server on the Usage Guides tab of the service details page when the service is running. However, this address is inaccessible from the client of the request initiator. As a result, the connection failed to set up and the domain name cannot be resolved.

Possible Cause

The addresses displayed on the Usage Guides tab page are the addresses of HUAWEI CLOUD API Gateway (APIG). The network between the client of the request initiator and HUAWEI CLOUD is disconnected.

Solution

If the client is out of the HUAWEI CLOUD network, ensure that the client can access the Internet.

If the client is on the HUAWEI CLOUD network, the address is accessible in the default network configuration. Do not configure special network settings, such as firewall rules.
