OpenGear OM1204 Uploading a SSL Cert via API V2 which has Intermidiate Chains

Trying to upload a SSL Cert via API v2 and keep getting error
“error”: [
{
“type”: 5,
“code”: 51,
“text”: “Certificate / Key combination failed validation”,
“args”: {},
“level”: 1

Cert has Chaining with multiple -----BEGIN CERTIFICATE-----…-----END CERTIFICATE-----

I have encoded CR s to \n and it works with initial CERT but can’t get chains in. Is this possible?
