I've currently got a floating IP pointing at a server hosting a number of sites, some with SSL, others without.
I need to shutdown, backup and resize said server - and was hoping to setup a simple holding page on a small VPS instance - swap over the floating IP, catching all the traffic and redirecting.
I had this running using 'servername _' as a wildcard to catch all domain names, however (despite the port being open) - I was unable to access the site at the HTTPS address - and when I added a scheme based redirect (directing to HTTP) - this didn't appear to have any effect?
Any help much appreciated. I imagine it's probably a relatively simple nginx server block.
