I'm trying to active Intellij IDEA (14) with my educational license under Ubuntu-gnome (15.4) getting an SSLHandshakeException:

JetProfile connection error: SSLHandshakeException: java.security.cert.CertificateException: java.security.SignatureException: Signature length not correct: got 256 but was expecting 512

Then it says "Intellij was not able to detect your proxy configuration", although I do not have a proxy and my network settings are configured to have no proxy. The support there told me to check my direct connection to https://lservice-auth.jetbrains.com/(https://account.jetbrains.com/lservice/). Chrome says this connection isn't safe (I've switched my distro and successfully activated Intellij, Chrome still has trust issues with that link):

NET::ERR_CERT_AUTHORITY_INVALID

Intellij-Error screenshot: enter image description here

Update: I have managed to import Jetbrain's Keystore to my keystore, it now has 2 entries but still won't work:

Keystore enthält 2 Einträge
