I haven't been able to play Minecraft on my Macbook Pro for around 4 days.
Whenever I try to login to my account, this is what appears:
Sorry, but we couldn't connect to our servers.
Please make sure that you are online and Minecraft is not blocked.
(SunCertPathBuilderException: unable to find valid certification path to requested target)
I have no idea what to do. I've searched on Google, but there was nothing about it, and tried contacting Mojang support, but they weren't any help either.
