I ran this command: sudo certbot --nginx -d domain name
It produced this output: There were too many requests of a given type :: Error creating new order :: too many certificates (5) already issued for this exact set of domains in the last 168 hours: houseradio.ru,www.houseradio.ru: see Rate Limits - Let's Encrypt
The operating system my web server runs on is (include version): Ubuntu
My hosting provider, if applicable, is: -
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
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 0.40.0
Please use one of the previously issued 5 certificates. It's not possible to reset the rate limits. This is also explained on the rate limit documentation page. Please read it.
Then you need to wait for a week from the time you issued the first one. And as Osiris says, do any future testing using the staging environment so you don't encounter this problem again.
