Microsoft Authenticator node, Error PKIX path building failed

Hello!

I Recently got approvals to connect to sharepoint using the microsoft authenticator node, it was working fine until I got to the office, where when we connect to the Corporate network we get the following error message: “ERROR Microsoft Authenticator 3:4 Execute failed: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.”

The problem only occurs when connected to that specific network, when working from home, or sharing internet from our cellphones it works without issues, so that points me that is something related to network configuration, I have raised a ticket with out IT team but they are not finding whats causing the issue… can someone help me with this issue?
