Installation error

[Easyfungamer]

Hello,

I tried to install forge on my windows machine and as it is halfway trough the download process, it says "javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target". Somehow it works on my linux machine. But I ran the installer on different Windows machines and faced the same error. I think it has to do with Let'sEncrypt. Please help me.

Thanks.

Thanks for your help, but I invetigated the issue again from scratch, so I fixed it. I swaped some .der files arround and added it in the cacerts file, so it's now up and running. Huge thanks to you for helping me!

Bye!
