It's working fine here, showing a Let's Encrypt certificate.

[QUOTE=Mini-Geek;477440][url]https://www.gpu72.com/[/url] is trying to use a self-signed certificate right now, which my MISFIT is, understandably, complaining about. Has something gone wrong with the server configuration?[/QUOTE]

Possibly. I'm consolidating two 1and1 dedicated servers onto one, so it's possible I messed up somewhere.

Are you still seeing this issue? Is anyone else?

Actually, I think I might know what's going on... Is there any chance your machine is running IPv6?

I configured gpu72.com's DNS to support AAAA records, but SSL Lab's SSL Report isn't liking the certificate for the IPv6 address, but gives the same cert an "A" rating when accessing via IPv4.

Hmmm... I'll remove the AAAA records until I figure out what's going on.

I figured it out. And as usual, it was a Stupid Human error...

I had the wrong IPv6 address in the virtual server configuration, so any SSL IPv6 requests were falling through to the default virtual server.

Thanks for bringing this to my attention. And, as an aside, I'm a little surprised how many people are running IPv6!

That's good news!

Yes indeed! You solved it. Thanks. :smile:

RIP little server...
 

So, I finally got all the various web servers off the original GPU72.com server, and decommissioned it.

I rebooted it into "recovery mode", and then through the serial console let it run nwipe for 24 hours (using Mersenne Twister as its PRNG; seemed appropriate). Not really needed, I know, but what the heck.

The poor little thing was not healthy; it couldn't even complete a SMART test of its drives. But still, it served me well; since 2011.

May you be recycled into something(s) useful.

gpu72.com seems to be down, including the proxy.

1&1 is doing some data centre upgrades tonight, that may explain gpu72 being down.
mersenne.ca is also down for approximately the next 6 hours.

Ah. Meltdown/Spectre related, I wager.

Not necessarily. The downtime was planned a month ago and described as:[quote]In order to keep our services secure and reliable, we need to perform maintenance on one of our data center’s power supply infrastructure. To conduct this procedure safely, we unfortunately will need to interrupt the power supply to your 1&1 Server on 20.01.2018. This maintenance will occur sometime between the hours of 11pm EST and 7am EST on 21.01.2018. Your server may be unavailable for 6 to 8 hours while the maintenance is taking place.[/quote]
