Certificates not showing names or certificate id’s on nginx server

After switching to nginx because of the extreme amount of memory usage of this plugin the pdf generation fpr the certificates seems broken. It still generates pdfs for the certificates but the name and the other information filled in by the tags don’t show and show a blank area instead. The other text and image shows fine. Also to note is the fact that everything seems to show in the preview where it shows me the admins name in the certificate. Could this be anissue with curl? Or a module that is required that is missing on nginx?
