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: subrogation.net

I ran this command:

It produced this output:

My web server is (include version): unknown, not hosted by me

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

My hosting provider, if applicable, is: Site Ground

I can login to a root shell on my machine (yes or no, or I don't know): no

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

I don't have access to the web server, but here is information that I know:
Valid Until: Feb 25, 2023 (-9 days)
Signature Algorithm: sha256WithRSAEncryption

Domain Name: subrogation.net
Issued By: R3
Organization: Let's Encrypt
Country: US

I have contacted the company that hosts the site, they say they don't manage the SSL
I have contacted the webdesigner, he says he doesn't manage the SSL
I am a new IT person for the company, I am just trying to get the site SSL recertified and not sure where or how to do that.

Hello @maybankcert, welcome to the Let's Encrypt community.

If you are using the HTTP-01 challenge of the Challenge Types - Let's Encrypt
Let's Debug is showing an ERROR for HTTP-01 https://letsdebug.net/subrogation.net/1398112 that Port 80 is not Open.
Best Practice - Keep Port 80 Open

If you are using the DNS-01 challenge Let's Debug is showing an OK https://letsdebug.net/subrogation.net/1398114

But I do not know which you used since this was not filled out

@maybankcert

I ran this command:

It produced this output:

I also suspect some dynamically changing environment on your side, like a "smart" firewall or possibly you are bring the system down and up.

But your server seems to be nginx.
