Issue Adding Subdomains to Working SSL Certificate

Hello everyone,

I would like to share an underlying issue I've encountered with Let's Encrypt, stemming from my attempt to add new subdomains to my existing SSL certificate.

I successfully obtained an SSL certificate for my main domain, and it was functioning properly. However, when I tried to add new subdomains, I faced difficulties as the process didn't work as expected. Subsequently, I started encountering rate limit issues.

Is there someone with experience who can help me understand how to resolve this issue? Are there specific settings or steps I should take to expedite the rate limit reset and add the subdomains correctly?

I would greatly appreciate any assistance or advice on this matter.

Thank you very much in advance,

I ran this command: --issue -d -d -d -d -d -d -w /home/myusername/public_html --server letsencrypt

It produced this output:
[Mon Jul 8 18:23:39 EDT 2024] Domains have changed.

Hi @Black01,

No, just wait.

Testing and debugging are best done using the Staging Environment as the Rate Limits are much higher.
There are also Failed Validation Limit - Let's Encrypt and Duplicate Certificate Limit - Let's Encrypt and Registrations Per IP Limit - Let's Encrypt

And to assist with debugging there is a great place to start is Let's Debug.


Hi @Black01
Maybe @Neilpang can help with this one.


Also @Black01 take a look at Adding domainnames (Alt Domain) with - #3 by 9peppe


Thank you all guys.
I have created a separate certificate for each subdomain
I know it's not the perfect solution but I think is fine for now.
because I tried all the solutions and they didn't work.
