Cardano-node gets no connection

Staking & Delegation Operate a Stake Pool
1

I created a docker container whilst following the tutorial at Start your node - Stake pool course

but it just keeps printing

[String "Failed to start all required subscriptions",String "SubscriptionTrace",String "\"relays-new.cardano-testnet.iohkdev.io\""]

i already tried telnet and it worked

i’ve downloaded the config files from Cardano Configurations

my docker-compose file looks like this

version: '3'
