How to fix it:    
 
  • check your internet connectivity and try to reload this page
  • necessary open firewall ports for signature services:
    • HTTPS (TCP Port 443) outgoing to https://sealserver1.xyzmo.com
    • HTTP (TCP Port 80) outgoing to http://ocsp.d-trust.net
  • necessary open firewall ports for verification services:
    • all outgoing ports (because the certificates to check may reference to any service)
