I've done follow on cisco guide Using ACME https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X12-6/exwy_b_certificate-creation-use-deployment-guide/exwy_b_certificate-creation-use-deployment-guide_chapter_0100.pdf , but the result (the picture below) : There was invalid response from Expressway E
