I followed the Harber's blog and newer had an issue. Make sure Certificate is properly issued and is in the cert store.
For Service Bus
# grab the certificate based on it's friendly name
$friendlyName = "wfmSanCert"
$cert = dir Cert:\LocalMachine\My | ? {$_.FriendlyName -eq $friendlyName}
# configure the certificates
Set-SBCertificate -FarmCertificateThumbprint $cert.Thumbprint -EncryptionCertificateThumbprint $cert.Thumbprint
# stop the service bus farm
Stop-SBFarm -Verbose
# update the service bus host(s)
Update-SBHost
For Workflow
# load up the Workflow Manager PoSh
Import-Module WorkflowManager
# grab the certificate based on it's friendly name
$friendlyName = "wfmSanCert"
$cert = dir Cert:\LocalMachine\My | ? {$_.FriendlyName -eq $friendlyName}
# configure the certificates
Set-WFCertificate -SslCertificateThumbprint $cert.Thumbprint -EncryptionCertificateThumbprint $cert.Thumbprint
# stop the workflow host
Stop-WFHost -Verbose
# update the workflow host(s)
Update-WFHost
# re-start the workflow host
Start-WFHost
