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. https://crt.sh/?q=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: crm.biotum.ru
My web server is (include version) nginx/1.14.0
The operating system my web server runs on is (include version): CentOS7
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’ve encountered one issue of getting a new certificate for my site. Usually I use the ‘sslforfree’ site to generate and obtain new certificates. But since last week all my attempts of getting the new cert have been failed. Every time I am getting the old one. I also have tried to get the new certificate with the certbot, but the result the same as described above. What’s the problem can it be? How can I resolve it?
Thank you in advance.
