My current config is completely failing…
Migrating from Zendesk where webhook integrations were just simple HTTP POSTs to a public URL. Now, with Genesys Cloud Private Connect (BYOC), the Edge seems to be rejecting outbound calls to our legacy CRM endpoint. The Zendesk workflow handled this gracefully, but Genesys Cloud is throwing a TLS_HANDSHAKE_FAILURE in the Edge logs.
The CRM endpoint uses a self-signed certificate for internal testing. In Zendesk, we just added the CA to the server trust store. Here is the current Private Connect configuration:
private_connect:
id: "pc-12345"
name: "Legacy CRM Connector"
endpoints:
- host: "crm.internal.local"
port: 443
protocol: "HTTPS"
tls_settings:
verify_certificate: true
ca_bundle: "/etc/ssl/certs/custom-ca.pem"
The Edge version is 22.4.0. When I test the connection from the Genesys Cloud Admin portal, it times out after 30 seconds. I suspect the Edge container cannot resolve crm.internal.local or the CA bundle path is incorrect inside the Docker container. Does Genesys Cloud require a specific format for the CA bundle, or is this a DNS resolution issue within the Edge pod? Need to map this Zendesk-style trust model to GC quickly.
Yep, this is a known issue… The Edge BYOC deployment enforces strict certificate validation by default. Unlike Zendesk, you cannot simply ignore self-signed certs. You must upload the CA bundle to the Edge Certificate Authority store in the Admin portal. Ensure the Trust Store includes the root CA, or the TLS handshake will fail regardless of the target URL.
Be careful with just dumping the root CA. That’s a quick fix but it opens a massive security hole. You’re trusting every certificate signed by that CA, which defeats the purpose of TLS validation. If your CRM uses a self-signed cert for internal testing, you should really be using a proper internal PKI or a wildcard cert from a trusted internal CA.
If you must proceed with the self-signed cert for now, ensure you’re uploading the full chain, not just the leaf. Also, check the Edge version. Older BYOC versions had bugs where the trust store didn’t refresh properly without a restart.
{
"action": "upload_ca",
"endpoint": "/api/v2/platform/truststores/certificates",
"note": "Ensure 'isTrusted' is true in payload"
}
Don’t ignore the TLS_HANDSHAKE_FAILURE logs. They usually point to a mismatch in supported cipher suites. Genesys Cloud edges prefer modern TLS 1.2+ with specific ciphers. Your legacy CRM might be stuck on TLS 1.0 or weak ciphers. You’ll need to update the CRM’s SSL config or accept the risk.
The trust store approach is technically correct, but there’s a compliance angle here that often gets overlooked in DevOps pipelines. If you’re in a regulated environment like banking, relying on self-signed certs for outbound CRM data usually fails an internal audit. It’s a violation of standard data protection policies.
You can patch the immediate TLS failure by adding the cert to the Edge CA store, but you should plan a migration to a proper internal CA. The Edge does support importing specific CA bundles, which is better than trusting the whole root.
Here’s how to check if the Edge has picked up the new cert. Run this against the Edge API:
curl -k -u "admin:password" \
https://<edge-host>/api/v2/edges/certificates
Look for the issuer in the response. If it’s missing, the handshake will keep failing. Also, check the Edge logs for javax.net.ssl.SSLHandshakeException. That confirms it’s a cert issue, not a network timeout.
Don’t forget to restart the Edge service after updating the trust store. The changes don’t apply immediately. And document this exception if you keep the self-signed cert. Auditors will ask why you’re allowing unverified connections to your CRM.
Thanks for the heads up on the audit angle. We’re in a regulated space, so the self-signed workaround is a hard no for us. Switching to our internal PKI is the only path forward. Appreciate the push for proper security hygiene over quick fixes.
