Hi,
It seems it was deprecated when LWP changed from 5.8x to 6.0. The culprit is LWP::UserAgent.
You can bypass the issue by downloading the SSL certificate from the vCenter and setting HTTPS_CA_FILE=MyCertFile.
Since there is -for now, I hope- what to disable the check enforcement on the LWP module, would it be possible to add the cert file as one of the standard parameters on the Perl SDK?
Cheers
César
