Hello,
I am trying to setup a wildcard letsencrypt on my Nginx running on ubuntu 14.04, the error is popping up after I am trying to validate the TXT record, it’s failing everytime.

Failed authorization procedure. digiblast.work (dns-01): urn:ietf:params:acme:error:dns :: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.digiblast.work

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: digiblast.work
   Type:   None
   Detail: DNS problem: NXDOMAIN looking up TXT for
   _acme-challenge.digiblast.work

My, domain name registrar is namecheap, and hosting is AWS . please help.

Regards,
Bhaskar

Hi,

Did you add the requested DNS record to your domain (in NameCheap)?

Thank you

Hi @bhaskarb

it's curious: You have created an entry with the correct name.

D:\temp>nslookup -type=txt _acme-challenge.digiblast.work.
_acme-challenge.digiblast.work text =

    "K-ut_4LrZo2MRG0rIpluDRc6HLM7BJw5vin6j9aaCVE"

Lower / upper isn't a problem.

D:\temp>nslookup -type=txt _ACME-challenge.DIGIblast.work.
_ACME-challenge.DIGIblast.work text =

    "K-ut_4LrZo2MRG0rIpluDRc6HLM7BJw5vin6j9aaCVE"

You didn't create a typical wrong entry:

D:\temp>nslookup -type=txt _acme-challenge.digiblast.work.digiblast.work.
*** _acme-challenge.digiblast.work.digiblast.work. wurde von fritz.box nicht gefunden: Non-existent domain.

But Letsdebug

can see three *.digiblast.work - certificates:

Serial: 424975080353586386072907275331994760098180
NotBefore: 2018-10-13 20:55:51 +0000 UTC
Names: [*.digiblast.work]

Names: [*.digiblast.work]

so it looks that it worked today.

Can you start a new order, create / change the txt entry. Then wait two or three hours before you confirm?

And: What's your client, what command did you used?
