SSL Certificate Errors

The computer which has the server is a freshly Windows 11 install, without any modding, no vpn, so very “plan vanilla”. At work, the computer of course has an antivirus (McAffee) that I have no control, and they have in place “something” for the networks. It is a big network, with 10,000+ more devices across multiple sites. Would a ipconfig /all on this machine help the troubleshooting ?
