Thanks for reporting @nonameb3 :)

Temporary Solution ->

Change hyperchain_wizard.ts + hyperchain_wizard.js to use localhost instead of geth + postgres urls ->

http://geth:8545
->
http://localhost:8545

postgres://postgres:notsecurepassword@postgres:5432/zksync_local
->
postgres://postgres:notsecurepassword@localhost:5432/zksync_local

Then re run zk stack init to create new chan with env file regenerated

Let me know if if that works for you.

We are further investigating this issue and will keep this thread updated.

Thanks, It works!
