1.20.4 I cant download Forge(all files)

[TrizHell]

If i try to download forge, I get an error by type - this is not a correct page, it was moved or deleted


problem is also that if you download forge.jar and try to install not the Client but the Server from it, he writes -
Error checking https://files.minecraftforge.net/: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Error checking https://launchermeta.mojang.com/: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
