Minecraft Forums

Okay so, one day I wanted to play Minecraft but is wasn't connecting to the internet, so I reinstalled Minecraft, deleted minecraft as a program and .minecraft in the roaming folder, and then I couldn't log in as i was saying it could not connect to the authentication servers. So I thought that my Kaspersky was blocking it through firewall, I tried making it as an exception, but it still wouldn't log in, so I turned Kaspersky off, and then I could log in. After I downloaded and ran snapshot 16w02a, I closed Minecraft and turned Kaspersky back on and tried to run Minecraft but the option I got was offline mode. So I went turned off Kaspersky and tried to launch again but it was stuck in offline mode on startup. I looked at the logs and the error code is as follows:

So what is it that is keeping me from connecting to the Mojang authentication servers?

When I log into minecraft it shuts me out and gives me this error: SunCertPathBuilderException: unable to find valid certification path to requested target

What do I do?

Make sure you are running the new launcher. Also, maybe it was a courrpt download so just re download it.

Already reinstalled it 2 times.

Thank you so much!! This worked instantly.

Quote from webrosc»

what antivirus are you using? ah your using kaspersky

If you are using Kaspersky Internet Security and cannot connect to Mojang's servers, turn off Encrypted Connections Scan by following this guide: http://support.kaspersky.com/9927#block1

(i unspammed your initial post which had the crash log and merged it with your other thread)

Thank you so much!! This worked instantly.

I Have The Same Issue Here Is my Log[/p]
