I am trying to run Cardano-node with preprod testnet configuration files from :

curl -O -J https://book.world.dev.cardano.org/environments/preprod/config.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/db-sync-config.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/submit-api-config.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/topology.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/byron-genesis.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/shelley-genesis.json
curl -O -J https://book.world.dev.cardano.org/environments/preprod/alonzo-genesis.json

I am using node version 1.35.3 on MacOS Monterey 12.4 using the command :

cardano-node run \                                                            
--config $HOME/cardano/preprod/config.json \
--database-path $HOME/cardano/preprod/db/ \
--socket-path $HOME/cardano/preprod/db/node.socket \
--host-addr 0.0.0.0 \
--port 1337 \
--topology $HOME/cardano/preprod/topology.json

I tried to change the host-addr and downloaded all the config files for preprod but still getting this error :

Preprod environment is currently is being relaunched, so you need to wait at least 2 more days from today(20-Oct-2022).
