Cannot access to external endpoint

Hello,

After create obc and public s3 service to load balance external IP, I cannot access to it.

alias s3='AWS_ACCESS_KEY_ID= AWS_SECRET_ACCESS_KEY= aws s3 --no-verify-ssl --endpoint-url https://:443'
s3 ls or connect via S3 browser app ==> Error: connection timeout.

Am I missing any other configuration part or do you have any ideas to fix it?

Regards!
