When I add SSL to this domain lms.maccic.ca this problem appears
An unexpected error occurred:
too many certificates (5) already issued for this exact set of domains in the last 168h0m0s, retry after 2024-09-27 21:56:15 UTC: see Duplicate Certificate Limit - Let's Encrypt
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
Just like it says, you've already issued 5 certificates for that exact list of domain names this week. Presumably, you're having trouble installing one of those certificates to whatever system you're trying to install it into? There are an infinite number of possible ways people can be trying to integrate Let's Encrypt, so without a lot more details it's hard for people here to help. If you're looking for more information on the rate limits that Let's Encrypt uses to ensure that people don't abuse their resources (accidentially or not), then read through that web page that the error message linked.
Please fill out the standard form that you should have seen as much as you can. When it asks for "ran this command" and "produced this output", it's really helpful to put everything down exactly. Copy text if it's a terminal-based program (and put between lines of ``` to make it code-formatted), or take screenshots if it's from some sort of graphical interface.

Hi @ahmed, and welcome to the LE community forum

Ok, I want a radical solution to activate it safely.
It looks like you got a fresh production cert about 2 hours ago.
And, your server is using it as shown by this: https://decoder.link/sslchecker/lms.maccic.ca/443
Do you still need help?
When posting text output from the command line, please copy and paste it as </> Preformatted text. Screenshots make it difficult to read the text. Failing to format it as </> Preformatted text also makes it difficult to read.
If so, what shows:
certbot renew --cert-name lms.maccic.ca --dry-run
