Error DNS problem: NXDOMAIN looking up TXT - Plugin dns-ovh


My domain is:

I ran this command:

certbot certonly --dns-ovh --dns-ovh-credentials ovh.ini --dns-ovh-propagation-seconds 60 -d

It produced this output:

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

 - The following errors were reported by the server:

   Type:   None
   Detail: DNS problem: NXDOMAIN looking up TXT for

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.31.0-2.el7



Hi @venizia03

looks like your propagation is too short.

Your zone ( )

Serial: 2019031814
Refresh: 86400
Retry: 3600
Expire: 3600000
TTL: 300
num Entries: 2

has a TTL of 300 seconds.

Perhaps add the


parameter, then certbot waits with the next step. So you can recheck your domain and test, if the _acme-challenge - entry is visible.


Does it find the file “ovh.ini”?
Are those credentials still valid?

Are you running certbot as root?


Yes to all your questions :slight_smile: I even regenerated the API keys just to be sure.



I used this command since a long time without issue. It started today. I will try your suggestions : adding a greater TTL in command and the debug challenges option.



Not sure what happened but after 2 other attempts, the command works. Maybe an issue with the OVH API?


Yep, that’s always possible. Monday-morning - API :wink:
