Minecraft All The Mods 8 Authentication Issues

[Brian Smart]

Heya, so i was running atm8 through curseforge end of last year and connecting to servers fine, i have recently returned to it and now i cant login into the authentication servers no matter what i try.

everything is updated and running fine i just cant login to authenticate. 

i can run normal vanilla minecraft and go into servers fine with no issues it just seems to be the atm8 auth issue.  here is my latest log file im hoping someone can help me figure out what is causing this issue or give me some things to try as ive tried multiple things on several sites but nothing has fixed the issue. my internet connect is fine i have no issues with anything apart from this game, my friend who lives 15mins drive from me in the same state of Australia can get it working on his pc but i cant seem to.

any advice would be great this has frustrated me greatly.

i can provide more of the logs if required

In order to root out one of the more common issues, we'll need to see your hosts file. Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.

2) Paste the following into the prompt that opens: 'notepad %windir%\system32\drivers\etc\hosts' (/etc/hosts on Unix systems)

3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.
