trying to get BYOC edge running in eu-central-1. followed official terraform module for aws, version 2.4.1. containers are up, health checks passing, but edge never moves past PENDING_CERTIFICATE in admin console. api response from /api/v2/edges/byoc/{edgeId} just returns 403 Forbidden with code EDGE_REGISTRATION_FAILED.
checked connector logs on the ec2 instance. seeing repeated tls handshake timeout errors when it tries to reach media.euc1.genesiscloud.com. port 443 is open, security groups look fine. strange thing is the edge_token in env vars matches what was generated in portal, but platform keeps rejecting cert chain.
in nice cxone this whole registration phase takes like two clicks and auto-provisions the certs. five9 just pushes the config via their cli. here it feels like we are doing manual cert juggling for no reason. pricing matrix says BYOC should cut our media costs by 30 percent, but right now it is costing us more engineer hours than just sticking with the standard us-east-1 edge.
tried rotating the secret via /api/v2/edges/byoc/{edgeId}/secrets. same result. the deployment_id in the cloudformation stack doesn’t match the edge_id showing in the ui. maybe a region mismatch in the aws kms key? or is the terraform module just outdated for the berlin region?
logs are spitting out io.netty.handler.ssl.NotSslRecordException: not an ssl record every 12 seconds. nothing in the architect flow is even using this edge yet, just trying to get the baseline healthy.
curl -v https://media.euc1.genesiscloud.com:443 from the bastion host works fine. so the ec2 subnet routing is probably okay. but the edge container itself keeps timing out.
last log line before the crash: 2024-11-14T09:22:15Z ERROR edge-connector - handshake failed: peer certificate expired
stop fighting the 403. that’s just the API masking the real issue. check your IAM role on the ec2 instance. it needs secretsmanager:GetSecretValue for the cert ARN.
that IAM fix cleared the 403. thanks. now the edge is stuck in PENDING_CERTIFICATE. checked the secret manager, cert is valid. any idea why it’s not picking it up?
nah, you’re still missing the secret manager permissions. the cert being valid in ACM doesn’t mean the edge connector can actually read it. the connector runs as an instance profile on that EC2. if that role doesn’t have secretsmanager:GetSecretValue and secretsmanager:DescribeSecret for that specific ARN, the handshake times out and it just sits there.
we hit this exact same wall last week when spinning up our ServiceNow sync pipeline. the terraform module sets up the ACM cert, but it forgets to attach the policy to the execution role. you need to explicitly allow the secret manager actions.
check your IAM role policy. it should look something like this:
make sure the ARN matches exactly what’s in your AWS Secrets Manager. even a slight mismatch causes the 403. once you add that, restart the byoc-edge container on the EC2 instance. it should pick up the cert within 30 seconds.
if it’s still stuck, check the /var/log/byoc/connector.log on the instance. look for secret retrieval failed. if you see that, it’s definitely the IAM role. if you see tls handshake timeout, it might be a network ACL issue blocking outbound 443 to the Genesys cloud endpoints. but usually, it’s just the missing permission.
we’ve been wrestling with these AWS IAM quirks for six years now. it’s always the smallest permission missing that kills the whole deployment.
The IAM role permissions are critical, but the certificate format is often the silent killer here. The BYOC connector expects the secret in Secret Manager to be a specific JSON structure, not just the raw PEM files. If the keys are missing or malformed, the handshake fails silently.
Verify the secret value contains these exact keys:
certificate
privateKey
chain
If you’re using Terraform, ensure the value attribute in the aws_secretsmanager_secret_version resource is a JSON stringified object. A common mistake is uploading the files individually instead of bundling them.
Also, check the time synchronization on the EC2 instance. NTP drift causes TLS verification to fail even with valid certs. Run chronyc tracking to verify sync. If the time is off by more than a few seconds, the edge won’t register.
Reference the “Bring Your Own Cloud” deployment guide in the Resource Center for the exact secret schema. It’s easy to overlook the chain requirement.
