Failed to create connection: dial tcp 127.0.0.1:4221: connect: connection refused

I’m stuck on Stage #cn2.

What is weird is that when running

codecrafters test --previous

it also runs stage CN2 successfully. But when running

codecrafters test

I get this error:

[tester::#CN2] Failed to create connection: dial tcp 127.0.0.1:4221: connect: connection refused
[tester::#CN2] Test failed

Output:

Hey @mole-480, looks like your repo is missing the required .codecrafters folder.

I’ve pushed a fix to your repo. You can run git pull to sync the changes.

Let me know if you’re still running into issues!
