ChatKit - getting 401s from verify_hosted and conversation

I’m getting Status: 401 and this response from the verify_hosted and the conversation calls?!?

{
“error”: {
“message”: “Invalid or expired chatkit ephemeral key”,
“type”: “invalid_request_error”,
“param”: null,
“code”: “invalid_ephemeral_key”
}
}

Has anyone seen this before and fixed it?!? Help appreciated :folded_hands:
