Please share your thoughts.

Thanks

Did you change anything on the command to start the Alphas?

Please share more detailed logs.

I did the standard starting procedure:

dgraph zero

dgraph alpha --lru_mb 2048 --zero localhost:5080

dgraph-ratel


Its the first time I started. I can actually enter to localhost:800 but mutations and quieries simply dont work.

And can you share the Alpha logs? At the end of the Zero logs you shared, it says that Zero was able to establish a connection to Alpha’s internal gRPC port 7080.
