Try killing your firewall/av that may be derping it up.

Also try runnign with the -Djava.net.preferIPv4Stack=true argument {tho this is defaulted in 1.8 so not sure if this will help}

No AV/Firewall installed. This was literally a 100% fresh/clean install. No router either, modem -> PC only.

Where can I find/implement the "-Djava.net.preferIPv4Stack=true" argument?

 

I appreciate your time in this.

Edit profile  → tick off JVM argument :
