SpiceDB "failed to listen on addr". What's wrong?

[jaycee999]

OS: macOS
Version: 11.5.2
BuildVersion: 20G95
Homebrew 3.2.14
Go - go1.17.1 darwin/amd64

I installed spicedb using brew according to the README and get a "FTL" error when I run the following:

spicedb serve --grpc-preshared-key "somerandomkeyhere" --grpc-no-tls

Output

8:46AM INF set log level new level=info
8:46AM INF set tracing provider new provider=none
8:46AM INF using in-memory datastore
8:46AM INF dashboard running url=http://localhost:8080
8:46AM FTL failed to listen on addr for gRPC server addr=:50051

Not being too familiar with the underpinnings of gRPC and Go, any insight into what might be causing this would be appreciated.

It's possible that you have something else running on port :50051 locally already. Could you try running with a different port to see if that works? Something like:

spicedb serve --grpc-preshared-key "somerandomkeyhere" --grpc-no-tls --grpc-addr=:50052

That worked! I'd tried modifying the port before but I apparently skipped over that one. 😫

Thank you 🙏
