Hello! I’ve got a brand spanking new VirtualMin instance setup.
I created the first virtual server and called it
liewrws02.bofhllc.net. It’s got a nice SSL certificate from Let’s Encrypt, and everything so far looks good.
But when I created a second virtual server and called it
ellenburg.io as a test, when VirtualMin went to request an SSL certificate from Let’s Encrypt, it failed the validation piece.
Trying to troubleshoot that and when I attempt to go to http://ellenburg.io/ I end up seeing the default website for
http://liewrws02.bofhllc.net instead. Which also explains why the Let’s Encrypt validation failed if the wrong website is being served.
Does anyone have any thoughts or ideas? Frankly I’m a bit baffled. I’ve never seen this with VirtualMin before.
I found the problem thanks to Gomez_adams.
I have IPV6 AAAA records providioned for the domain but the server (while it has an ipv6 address) wasn’t setup and configured to use ipv6 completely so some traffic was hitting ipv4 (and working) but other traffic was hitting ipv6 (like mine) and wasn’t working.
Once I removed the AAAA records from the domain everything now is working as it should.
