I’m having this same issue with apache. I’m not quite following enough to understand what I need to do to fix it. Is it based on my DNS server capabilities? (I’m not allowed to link yet, but it’s github issue #1228)

Just linking: [image] Issue: Failed auth with urn:acme:error:unknownHost, but domain is easily resolved. opened by coolaj86 on 2015-12-06 closed by coolaj86 on 2015-12-09 I own blog.coolaj86.com which points to 67.166.110.237 (which happens to port-forward to a Raspberry Pi in my house). As a sanity check...

Do your nameservers use mixed case ( upper and lower) for your domain name ?

Does not look like an routing problem. Maybe an routing issue to the name server ? set type=ns coolaj86.com Server: UnKnown Address: 127.0.0.1 Nicht autorisierende Antwort: coolaj86.com nameserver = ns1.redirect-www.org coolaj86.com nameserver = ns2.redirect-www.org server ns1.redirect-www.org Standardserver: ns1.redirect-www.org Address: 192.241.238.7 Blog.coolaj86.com Server: ns1.redirect-www.org Address: 192.241.238.7 Blog.coolaj86.com nameserver = ns1.redirect-www.org Blog.coolaj86.com nameserver = ns2.redirect-www.org ns1.redirect-www.org internet address = 192.241.238.7 ns2.redirect-www.org internet address = 66.172.33.29 Blog.cOolaj86.com Server: ns1.redirect-www.org Address: 192.241.238.7 Blog.cOolaj86.com nameserver = ns1.redirect-www.org Blog.cOolaj86.com nameserver = ns2.redirect-www.org ns1.redirect-www.org internet address = 192.241.238.7 ns2.redirect-www.org internet address = 66.172.33.29

I think that’s the domain name of the original issue 1228 ( closed ) … not the current posters domain ( unless I’m not understanding )

My DNS is hosted on http://freedns.afraid.org/. They seem to resolve regardless of the case when I test them. @serverco correct, those aren’t my domain names. I’d rather not reveal mine at this time.

Can you give us the command you are running ( with your domain name changed) and the exact errors it gives please ( again with domain name changed) This is so we know what client you are using ( I’m assuming the main LetsEncrypt client, but don’t know ) and ehat arguments you are passing to it, as well as the exact error messages so we can help debug.

Thanks - and does everything show up correctly ( no errors) is you check your domain at http://www.intodns.com/ or http://dnscheck.iis.se/ ?

Just to add one more DNS checker to the list http://www.dnsstuff.com/ :wink:

Always a good one :slight_smile: ( although I preferred it slightly when you didn’t need to sign up … that’s going back a few years though :wink: )
