AWS EBS Deploy: Update environment operation is co

Question

I've been dealing with this issue since yesterday. All working until 4 PM and suddenly after that this error keeps coming.

Creating application version archive "882a".
Uploading: [##################################################] 100% Done...
INFO: Environment update is starting.                               
INFO: Deploying new version to instance(s).                         
INFO: Command execution completed on all instances successfully.    
INFO: New application version was deployed to running EC2 instances.
ERROR: Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.

No logs has been logged after that. Even there are no logs coming in AWS management console. I ssh the instance and checked all the logs /var/log/, they all have logs only until 4 PM.

So this is possibly a dead end I'm stuck with. I tried rebuilding the environment but no luck. The forum discusses this, but all troubleshooting is happening behind the screens, no possible solutions provided.

Any idea on how to resolve this?
