Hi l0rdraiden,

Thanks for reaching out to the Sophos Community Forum. 

If this is the initial installation you're trying, do you know if white-listing has already been done on the surrounding network environment? 
- Domains and ports to allow

You can also try accessing the update site manually through a web-browser to verify if it should be accessible on the affected device. 
- http://dci.sophosupd.net

Ports 80 and 443 are open, there is no web proxy so all the urls are allowed

I can reach from the server

http://dci.sophosupd.net

Sophos dci Site

Connection Successful

Is a clean installation of windows server 2022 datacenter edition

I think the error is here but I don't know what DCI is.

If this is a fresh installation of Windows Server, I suggest checking if your server recognizes the certificate the installer is signed with. This may be contributing to the issues you're experiencing. 

Ok, I found this article

I have followed it but I still get this errors, I installed the certificate that comes with the installer

Were the following steps successful when accessing the digicert website? 

1. Open an internet browser session.
2. Access this website.
3. If you see the following response, the root certificate is trusted and the installation/upgrade should complete on the next update:....

I suspect you will need to install the root certificate, which is the parent in the certification chain and allows the installer to be verified. This is the "DigiCert Trusted Root G4" certificate. 

I have downloaded this cert and installed this cert and the problem persist, any other idea?

cacerts.digicert.com/DigiCertTrustedRootG4.crt

There may be an issue on the license side. I've reached out to you via PM to inquire further.
