The problem of obtaining Let's Encrypt certificate


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., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version): Nginx

The operating system my web server runs on is (include version): CentOS 7.2.1511.el7.centos.2.10 (x86_64)

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): ISPmanager Lite 5.142.1

Used this instruction’s_Encrypt
When trying to get a certificate, we receive a message
During the process of obtaining Let’s Encrypt certificate avtozam.com_le2 an error occurred: Type: ‘missed’ Object: ‘unknown’ Value: ‘’.
What you need to check? What to look for to correct this error?
