@binygreenberg I haven't encountered this error before.

Based on quick Googling, perhaps it is related to your environment. We validate on https://docs.confluent.io/current/tutorials/cp-demo/docs/index.html?#run-demo . In your environment, what are:

1. OS version
2. Docker version
3. Docker Compose version

I am also facing an issue with "./scripts/start.sh". Please could someone help me with this, as I have been experiencing issues in trying to run cp-demo for a few days now. I keep getting the following warnings whilst running this script, but not sure if these are significant and how I can solve these:

WARNING: The ZOOKEEPER_SSL_CIPHER_SUITES variable is not set. Defaulting to a blank string. WARNING: The SSL_CIPHER_SUITES variable is not set. Defaulting to a blank string. WARNING: The CONNECTOR_VERSION variable is not set. Defaulting to a blank string. WARNING: The CONTROL_CENTER_KSQL_WIKIPEDIA_URL variable is not set. Defaulting to a blank string. WARNING: The CONTROL_CENTER_KSQL_WIKIPEDIA_ADVERTISED_URL variable is not set. Defaulting to a blank string.

Ultimately, I get the error, "The logs in control-center container do not show 'Started NetworkTrafficServerConnector' after $MAX_WAIT seconds. Please troubleshoot with 'docker-compose ps' and 'docker-compose logs'.\n"". I am not sure how to solve this

My environment versions are:

1. OS Version - CentOS Linux 7 (Core)
2. Docker version 20.10.1, build 831ebea
3. docker-compose version 1.18.0, build 8dd22a9

@mjthompson2107

1. Which branch of cp-demo are you using?

2. Please use 6.0.1-post branch and refresh the code:

git checkout 6.0.1-post
git fetch
git pull

Thanks error has now been resolved. I removed the clone and cloned again using the details you have provided. Not sure which version I was using before, but think it might have been this version and not sure what I had changed that caused it to not work

However, I am now getting this error:
