I have this issue aswell and I have uninstalled minecraft, java and then reinstalled them. I have also installed jave 17 but it still has a problem. If you could help that would be great.

[xeoticz]

You posted in a random unrelated thread and you have not provided any details besides "I have a problem".

Please make your own thread instead of posting in this one and post the log file you get and any error messages.

"I have the same issue" is what I said, if you need the log file here it is

Failed to run processor: javax.net.ssl.SSLHandshakeException:PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Once again I am saying I have the same issue, key part in this is "Failed to run processor: javax.net.ssl.SSLHandshakeException:PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"

If you could help me with this then I would really appreciate it.

Im guessing you don't have an answer.

Either way, I'm glad someone atleast noticed.

Patience, young padawan. And you are still posting in the same thread. Please follow my instructions. I will create a new thread for you.

Please go to https://launchermeta.mojang.com/mc/game/version_manifest.json in your browser and inspect the HTTPS certificate (usually you can find it by clicking the lock icon next to the URL).

Please post the valid from and valid to dates as well as the fingerprints. Ideally just a screenshot. You can use https://imgur.com/ to post screenshots.

It should look similar to this (mine is in German, but that doesn't really matter):

You are being subject to a Man in the Middle attack. The certificate you are being served is not the correct certificate for mojang.com.

This might be through your anti virus software (disable it to check, but some do not get fully disabled, so removing them is the only option). It might also be your ISP. In either case I would highly recommend switching the service as this is absolutely unacceptable behavior on their part.

Thank you for your amazing custumer service.

I have recently tried installing forge onto a  cracked client, suprisingly it worked! Do you know the reason to this? If so please let me know.
