Minecraft and Java : problem to connect with mojang server

Hi, I'm actually facing a problem with minecraft to connect to some of the mojang's server. In particular the authentication server and perhaps the skin server. When I connect to the game's server of one of my friend I'm reject with the error "the authentication server are down for maintenance" which is false because I can check the servers on mojang site : https://help.mojang.com/
When I'm on singlelayer mod my custom skin would not load.

What make me think the problem come from java is the bug report when I launch a singleplayer map :
MojangBeug.rtf
Bug report
(4.72 KiB) Downloaded 135 times
(it's a .txt in fact)
But I'm quite a newbie and I do not understand a lot of this.
Did someone can explain and have an idea on what's going on ?

I tried to use two different version of java :

openjdk version "10.0.1" 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)


which came install with linux mint 19 cinnamon and :

openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)


which I install whith apt. The problem was here on both of them.

PS : sorry for the english, not my native language ^^

I'm experiencing the same thing on Mint 19. I can connect fine with a Windows 10 machine to the same server in question but not from Mint. The only error i'm getting is the authentication servers being down which they obviously aren't.

Ok I succeed to get it work by manually installing oracle java 8 instead of OpenJDK (I find how to do this on the ubuntu wiki). Apparently the problem is with openJDK, I try to find doc to fix it and I search the error on the net but it was quite hard to understand. I didn't wanted to install Oracle java but as far as I am today I don't find any other solution.

Would you be able to provide the link to the forum post you followed? I have the same issue and am unable to find anything related to it.
