Forge Modloader showing javax.net.ssl.SSLHandshakeException error

StizzurpXDD · November 15, 2023

I am trying to download Forge 1.20.1 version 47.1.3. When I am installing it, in Building Processors, I am getting an error saying:-
Failed to run processor: java.net.ssl.SSLHandshakeException:PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to request target See log for more details.

I have tried everything. I reinstalled JDK and JRE to its latest version, I changed the firewall settings, I added the minecraftforge.net certificate to cacerts file, I used Jarfix still, nothing is working. Please let me know what should I do.
OS - Windows 11 64bit System

JDK Version - 21 x64

JRE Version - 8u391 x64
