A FastL4 virtual passes traffic without proxying, so packets on the server-side have the same TCP options as the client side packets.
A Standard virtual establishes a full connection on the client-side, and the server-side TCP options may be different to the client-side options. This may cause problems with packet fragmentation and reassembly that can interfere with SSL negotiation. You would need to collect a packet capture to be certain about what is happening.
I'd generally recommend FastL4 virtuals for SSL passthrough, as opposed to Standard virtuals, for this reason.
