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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: sherifshalaby.tech
I ran this command:
It produced this output:
My web server is (include version): apache
The operating system my web server runs on is (include version): centos7
My hosting provider, if applicable, is: dedicated server
I can login to a root shell on my machine (yes or no, or I don't know): root
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): whm/cpanel
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): No
All should be explained in the linked documentation. If you have any specific questions, fire away, but generic "how do I fix that" should be explained plentiful there.
This is also explained in the rate limit documentation. Note: the processing of the rate limit exemption forms can take some time I'm afraid. Also note that most users here on the Community are just volunteers and not actually Let's Encrypt employees.
It's not possible, as explained in the documentation, to manually increase or "reset" the limit on short notice.
I know that this is the community, I do appreciate the efforts done by everyone here, yet, being a community doesn't mean deeper support is impossible or restricted
Anyway, thank you for your hints
To keep the cost "free" Let's Encrypt has a small staff and relies on this community and automation. People needing rate limit exceptions occurs regularly and is handled with the Rate Limiting Form described in the pages Osiris already linked. In case you missed the link for this form, it is (here) described in the Overrides topic (link here).
