Disaster... Too many certificates tried on one domain

Can I roll over back with SSL? I totally regreted…
I tried too mand time to add certifications until the limit warning came out.

My domain is: sanmau.net

I ran this command: sudo certbot --apache-d sanmau.net -d www.sanmau.net
(I tried this too many times over and over again, and even rebuilt the Ubuntu for serval times, forgive I’m totally newbe and I hate myself now what if I had never tried to install SSL -_-!!!)

It produced this output: many errors in red type. too many certificates on the domain of www.sanmau.net and told me to view the log file… I’m totally a disaster maker…

My web server is (include version):

The operating system my web server runs on is (include version): Ubuntu 18.04 LTS Server - 64 Bit

My hosting provider, if applicable, is: Cloudcone

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no, i use ssh via putty

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.28.0

Hi @callenbit


isn't a disaster. There is only one certificate created (one pre- and one leaf certificate is listed).

So you have hitted the 5 failed / per account / per hour, wait one hour.

You can create 5 identical certificates in one week, so you can create 4.

Or use that certificate.

I think OP could mean the www certificate:

Rate Limit Current Status Domain
50 Certificates per Registered Domain per week OK (6 / 50 this week.) sanmau.net
5 Duplicate Certificates per week Limit exceeded. Next issuable at 09 Mar 2019 07:56:20 UTC www.sanmau.net

Maybe try add a space between the “apache-d” in the command you posted?

Thank you a lot! I feel a bit better now. I shoud read more instruction and manual book before I tried a command any more. Thank you, sir. I might post more details after I tried to make it right, whether success or not.

Maybe the “space” between apache & -d is the key problem in deed, thanks for you tested my www-domain and your tips. I will try again at 9 Mar follow your instruction. Thanks for your kindness!

If the space was the problem, there would be no need to wait (since a certificate with both versions of the domain correctly added would not be considered a duplicate).

At most you would need to wait 1 hour, as already mentioned.

You should test your configuration at:


  • Congratulations! Your certificate and chain have been saved at: …

It seems OK now. I will go on with wordpress installing. THANKS A LOT!

Yep, looks like

you have created 4 certificates only with www. But the combination of both domain names -> is new, so you have created one certificate with both domain names:

And you have installed a new Letsencrypt certificate:

expires in 90 days	sanmau.net, www.sanmau.net - 2 entries

So both connections are secure.

In case it hasn’t been mentioned, or if you are not aware, there is an entire staging environment that is designed and operates specifically for “testing”.
