Problem with my puppet agent 7.27 on a Windows client

[puppetstan]

Hi,

I have a problem with my puppet agent on a Windows client

I installed the puppet agent on my windows client.

I downloaded it here : https://downloads.puppetlabs.com/windows/puppet7/index.html

I took the following version : puppet-agent-x64-latest.msi

here is the installed version

C:\Users\Administrateur>puppet -V
7.27.0


My puppet file (puppet.conf) is in this directory C:\ProgramData\PuppetLabs\puppet\etc


[main]
server=puppet.domain.fr
autoflush=true
environment=production


when I force the puppet agent I get the following error

C:\Users\Administrateur>puppet agent -t
Error: certificate verify failed [unable to get issuer certificate for CN=Puppet CA: puppet.domain.fr]
Error: certificate verify failed [unable to get issuer certificate for CN=Puppet CA: puppet.domain.fr]


Do you have an idea of ​​the problem?

Regards
