No longer able to connect when using 0.3.6

Bug Description

When launching version 3.6.6 the bot is no longer able to connect to Discord, as the following errors begin scrolling through the logs:

[14:11:21] [ERROR] [SessionControllerAdapter]: Failed to establish connection for a node, appending to queue

Steps to Reproduce

Launch MusicBot with:

java -Dnogui=true -jar JMusicBot-0.3.6.jar

Expected Result

Expect that the behavior should match previous MusicBot versions, only this version appears to have this problem.

Checklist

• I have looked for information about this within the documentation
• I have searched for similar issues on the issues page
• I am running the latest version of the bot:

The certificate of the peer (CN=www.chinanetcenter.com) does not match the expected hostname (gateway.discord.gg)

Something is re-routing your traffic from Discord to chinanetcenter.com. Are you behind some firewall or proxy that blocks access to *.discord.com, *.discord.gg, *.discord.media and other Discord domains (such as the great firewall of China)?

[yamamushi]

This seems to have been related to a possible DNS poisoning attack, which was fixed with:

# /etc/init.d/dns-clean start
Running 0dns-down to make sure resolv.conf is ok...done.
