Hi Alex, your solution has been working well, until I had to renew my certificates through the server app, after that within a few days all the web services reverted to showing the default server webpage. After a bit of fiddling I tried unlocking all of the site files and adding the new certificates, they instantly started working again, what did surprise me though is that the non SSL sites also failed but then started working as soon as they were unlocked, not sure how that would happen but just thought I'd put it out there in case anyone else has the same issue
I am having issues connecting anything beyond a single Pegasus 2 to the Thunderbolt chain so I have had to do all the Target Disk Mode mirroring using a FireWire cable.
With the original Pegasus series this did not seem to be a problem. Have a trouble ticket in with Promise now.
