Dgraph-ratel unable to connect to dgraph server on localhost

@MichelDiz

http://localhost:8000 is working.
i can see the dgraph ratel, only it cant connect to https://localhost:8080 within the connector address of ratel

something like this below, except if i use https with port 8080, it will fail.
could this because im using self signed tls on caddy?
