In AWS Elastic Disaster Recovery - how to fix "Start reversed replication" failure "Verify the agent is installed and running"?

In certain cases, following an attempt to perform a reverse replication action, you will receive an error message indicating that the AWS Replication agent is not connected to AWS Elastic Disaster Recovery. In this case, verify that:

1. The agent is installed and running
2. The server is connected to the internet or the NAT gateway

Further,the recovery instance will require to allow an inbound connection on port 1500 from the source environment which can be via VPN/DX or via public IP.

Further, I request you to please check the following:

• Check the routes to metadata connectivity on the Recovery Instance.
• Restart the AWS Replication service.

Also, if the issues still persists, please get back to us with the latest agent log from the recovery instance on a support case.

1. DRS Source ID (starting with s-xx) associated with the recovery instance.

2. DRS agent logs located at (/var/lib/aws-replication-agent/agent.log.0)

3. DR AWS Region

4. What type of DRS setup in use - => AWS to AWS (cross Availability Zone or Cross Region): => On-premises to AWS:

5. Confirm all the agent processes are running in recovered instance: $ ps aux | grep aws-replication

I can confirm that the recovery instance has "AWSElasticDisasterRecoveryRecoveryInstancePolicy" attached to the role "AWSElasticDisasterRecoveryRecoveryInstanceRole".

Hence, additional details are required further to troubleshoot the current issue.

Hi, thanks for the info/suggestions

When I checked this morning the agent was not running (noting from "ps aux | grep aws-replication") but I believe it must have run originally as the instance appears in the "Source Servers" of the original primary region.

I have restarted the agent ("sudo /var/lib/aws-replication-agent/runAgent.sh") and now the instance in "Source Servers" show's "Rescanning".

Can you possibly indicate how I check these:

• Check the routes to metadata connectivity on the Recovery Instance
  - I have successfully run nc -zv X.X.X.X 1500 but do you mean something else?

• Restart the AWS Replication service. - does this mean the Agent on the instance or some other region wide service?

Edit:

I am wondering if I misstepped by reinstalling the agents once they had "recovered" over to the second region. Should I have just done a "Start reverse replication"?
