Potential problems described below # IP does not match

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:cs.isatel.tj

I ran this command:bbb-conf -check

It produced this output: Potential problems described below

IP does not match:

IP from ifconfig: 192.168.36.129

/etc/nginx/sites-available/bigbluebutton: cs.isatel.tj

My web server is (include version):nginx 1.10

The operating system my web server runs on is (include version):ubuntu 16.04

My hosting provider, if applicable, is:isatel.tj

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):0.31.0

I am new to this area. You can explain it more simply and in detail.

Hi @shohrukh

Do you own isatel.tj or are they your hosting provider? Possibly self hosted?
There is DNS records for isatel.tj but not for the subdomain cs.isatel.tj.

  1. Do you have your own registered domain name?

  2. Do you have a publicly accessible IP address?

  3. If so you’ll need to configure that IP in your network settings

192.168.XX.XXX lives in what is called “private IP” space. As such it cannot be used to access your website/server or obtain a certificate.

These things need to be setup correctly to move forward.
Someone will correct me if I am in error, I guarantee it!

Hope this helps

OR
If you do own this name and do need to only use it internally and somehow require a valid cert, you can try using DNS authentication - HTTP authentication requires a valid Internet accessible IP.

Thanks for the answer.
I work in a VMware virtual machine. This is my trial version. I created a domain name for myself in the hosts folder but I don’t know if this will work. Will the server in the virtual machine work?

Hi @shohrukh

that can't work. There are a lot of checks of your domain, last is two hours old - cs.isatel.tj - Make your website better - DNS, redirects, mixed content, certificates

Host T IP-Address is auth. ∑ Queries ∑ Timeout
cs.isatel.tj Name Error yes 1 0
www.cs.isatel.tj Name Error yes 1 0

There is no public visible ip address -> you can't use http validation.

Start with some basics:

Then read something about challenge types:

http validation -> public domain name -> public ip address of your server -> Letsencrypt tries to check your domain via your server.
