Not able to Connect to gRPC Service hosted as Azure app Service using gRPCurl Tool

I am trying to connect to the gRPC service which is hosted as Azure App Service using grpcurl, It gives the below error
Failed to dial target host "hostname:8585": context deadline exceeded.
Where As If I try the same in postman or if I create a console application by following the steps mentioned in below documentation [https://learn.microsoft.com/en-us/aspnet/core/tutorials/grpc/grpc-start?view=aspnetcore-6.0&tabs=visual-studio#create-the-greeter-client](https://github.com/fullstorydev/grpcurl/issues/url) I was able to connect to the service. Anyone, please let me know how to connect to the gRPC service hosted in Azure using the grpcurl tool
