Is it possible to clone a GitLab repository hosted in a subdomain with GitExtensions?

I have a subdomain where GitLab is installed, I need to clone a repository of that subdomain but GitExtensions gives me the following error:

"C:\Program Files\Git\bin\git.exe" clone -v --recurse-submodules --progress "subdomain" "C:/Users/mramosga/Desktop/tests_caj/tests_caj"
Cloning into 'C:/Users/mramosga/Desktop/tests_caj/tests_caj'...
fatal: unable to access 'subdomain': schannel: next InitializeSecurityContext failed: SEC_E_UNTRUSTED_ROOT (0x80090325) - The certificate chain was issued by an authority that is not trusted.
Done
