I don’t know much about the working mechanism of GRPC in APISIX, and I’m not sure if It will use local DNS resolution.

BTW, You can try to use pod IP instead of internal domain name configuration to upstream. @riskgod

@riskgod A little embarrassed, I misunderstood the output of `nslookup` , actually the `grpc-node` service was resolved correctly (target IP address: `10.99.252.250`).
So have you try to access grpc-node through APISIX? if so and it's abnormal, please paste some error log of APISIX.

@riskgod The above problem is not related to DNS. The problem `404 Route Not Found` means you don't configure a Route correctly, or you have configured one but you don't use correct URI, Host when you send a request to APISIX.
Also, please paste your Route configuration.
