Hi,
I'm also having this issue with the reloadSslCertificate method.
I've read that you want to reinstall your vcenter. just to let you know that it is after a reinstallation that I cannot change the SSL cert with a SSL that already changed in 5.1.
maybe a new issue with 5.5...
I'll open a SR to see why I cannot change this Cert.
let you informed.
Eric.
