Ubuntu Server 18.04

gigihont@ubn:~$ dgraph version

I using type to connection “Bridged Networking” in virtual box.

I started zero, alpha and ratel

My ip addr is:

When I try to use ratel, it can’t connect to the server

Go client works fine.

What is the URL in “Enter Dgraph server URL:”? (Ratel)

[vladimir]

gigihont@ubn:~$ dgraph-ratel -addr=192.168.1.97
Error parsing Dgraph server address: host is empty

I use command:
dgraph-ratel

[MichelDiz]

The URL must be like:

192.168.1.97:8080

[MichelDiz]

oh, I’m not talking about this. I’m talking about Ratel. What address have you added in the panel “ Enter Dgraph server URL: ”?

[vladimir]

gigihont@ubn:~$ dgraph-ratel -addr=192.168.1.97:8080
Error parsing Dgraph server address: parse 192.168.1.97:8080: first path segment in URL cannot contain colon

[MichelDiz]

Don’t start ratel with this addr command (don’t even need it). And that’s not the point. What only matters is the address in the UI. Not in the command that starts the UI.

You have it pointed to 192.168.1.97:8000 which is the same address of Ratel UI. Instead, you should use 192.168.1.97:8080 which is the Dgraph HTTP API. Just switch this and you good to go.

[vladimir]

Oh, It works perfect.
