I'm having problems issuing a certificate for this domain mkt.lxpack.pt, even though on DNS checker it shows as propagated all around the world, and even in Let's Debug it shows just fine, but when issuing the certificate it's returning this error:
mkt.lxpack.pt:Verify error:DNS problem: query timed out looking up A for mkt.lxpack.pt
If I curl the acme-challenge URL from an external source I can get the challenge just fine, it's seems it's just let's encrypt servers that can't.
Can anyone help with this issue?
Also we generate certificates for several other domains, this problem only seems to be happening on this one.
My domain is: mkt.lxpack.pt
I ran this command: /root/.acme.sh/acme.sh --issue --debug --stateless --key-file /etc/pki/tls/private/test_mkt.lxpack.pt.key --fullchain-file /etc/pki/tls/certs/test_mkt.lxpack.pt.crt -d mkt.lxpack.pt
It produced this output: mkt.lxpack.pt:Verify error:DNS problem: query timed out looking up A for mkt.lxpack.pt
