Could not list EM ceritifcate directory '/shared/em/ssl.crt' in function LoadEmCertificates: Permission denied

Hi i don't remember 100% how we resolved this. But one thing I remember is that when we have successfully established GTM comminucation & iQuery, after a week my client changed the certificate uploaded on all of the GTMs and that is what caused the issue(i think). So what we did was, renew the device certs on all gtm devices and established GTM & iQuery again.
