Can't build GMC image due to go mod download failure

[weichengintel]

I'm trying to set up GMC (GenAI Microservices Connector) following the instructions in the README, but I'm encountering an error during the Docker image build process. Specifically, I can't download the Go modules while building the Docker image.

Steps to Reproduce

cd GenAIInfra/microservices-connector
make build
make docker.build

Workaround

As a temporary workaround, add --build-arg https_proxy=$(https_proxy) --build-arg http_proxy=$(http_proxy) to lines 122 and 127 in the Makefile:

# Build manager Docker image
manager-image:
	@echo "Building manager Docker image..."
	$(CONTAINER_TOOL) build -t $(DOCKER_REGISTRY)/${CTR_IMG}:$(VERSION) --build-arg https_proxy=$(https_proxy) --build-arg http_proxy=$(http_proxy) -f Dockerfile.manager .

# Build router Docker image
router-image:
	@echo "Building router Docker image..."
	$(CONTAINER_TOOL) build -t $(DOCKER_REGISTRY)/${ROUTER_IMG}:$(VERSION) --build-arg https_proxy=$(https_proxy) --build-arg http_proxy=$(http_proxy) -f Dockerfile.router .

Network issue.
Could we close this?
