Answer 1

are u on the correct git commit?

did you start the server first?

in the terminal, before entering to nix-shell do this to go to the correct git commit: in the plutus-apps directory:

git checkout 41149926c108c71831cfe8d244c83b0ee4bf5c8a

then 3. At top of this repo

nix-build -A plutus-playground.server

4. Enter

nix-shell

only then start the server

cd plutus-playground-client

plutus-playground-server

Wait for server to start, it'll log "Interpreter ready" 5. In second terminal at top of this repo, enter

nix-shell cd plutus-playground-client npm run start Wait for the client to start, it'll log "webpack compiled with …”
