• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.

when I try to pass the debug it tells me this

I think I have the server properly configured with IPv6, but I don't know what to think


.\curl.exe -6 aceval.eu

return this

curl: (7) Couldn't connect to server


Any ideas or help.

Thank you
 
aceval.eu has an AAAA (IPv6) record (2001:41d0:203:4b76:)

But I see:

# host aceval.eu
aceval.eu has address 51.83.2.118
aceval.eu has IPv6 address 2001:41d0:701:1000::14cb

Are sure that AAAA record is correctly configured in DNS settings?
 
My result this command

# host aceval.eu
aceval.eu has address 51.83.2.118
aceval.eu has IPv6 address 2001:41d0:203:4b76::
aceval.eu mail is handled by 10 aceval.eu.
 
My result this command

# host aceval.eu
aceval.eu has address 51.83.2.118
aceval.eu has IPv6 address 2001:41d0:203:4b76::
aceval.eu mail is handled by 10 aceval.eu.
Yes, I see the same now.
Is the problem still actual?
 
Do you have an enabled firewall? Try to disable it.
 
@Creativados ,
please be sure that your site available via IPv6.
LE has a priority: it uses IPv6 in case AAAA record exists. so it looks like some misconfiguration on your side.
 
You have a firewall and dns (your two nameservers have different config for this domain) and/or ip configuration problem
I randomly get "2001:41d0:701:1000::14cb" or "2001:41d0:203:4b76::" as the AAAA record for aceval.eu, depending on the nameserver I ask.

And on both IPv6 addresses your webserver is not reachable... (IPv4 is OK)

It was a server configuration error, but I don't know how to get rid of that IP trace

with what NS do you get that name resolution?
