Impossible to generate a SSL certificate (wildcard)

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: i had a Let's Encrypt certificate fir my domain name, but it did not apply to the www subdomain. So I asked to generate a new certificate using the "wildcard" option, but an error message showed up.

It produced this output: here is the error message:

Welcome to the Let's Encrypt Community, Suzie :slightly_smiling_face:

It seems like your previous TXT records for aren't being cleared out before attempting a new DNS-01 challenge.

You can see that here:

  1. Clear out the old TXT record(s).
  2. Proceed with the new TXT record(s).

And if all you want is the www subdomain, you don't need a wildcard. You can just use a "normal" non-wildcard certificate that has both the www and non-www names on it. Usually that's easier, unless you actually need to use a wildcard.


Thanks to both of you! With your help, I've been able to regenerate a new certificate, and it works just fine! Thanks!


You are quite welcome! :blush:

Now that you've successfully generated your new certificate, you can go ahead and clear those TXT records (if you haven't already). They're one-offs that won't be reused and are unnecessary to keep.

It looks like you successfully generated a non-wildcard certificate per @petercooperjr's excellent advice:

And then, if you're using DNS-01 authentication, see if you can automate the process of adding and removing the records, or else you may be in the same spot in a couple months.

(If you're using HTTP-01 authentication now, then sure the TXT records are just superfluous.)
