Need computer nerd help (Internet Problem?)

[Paper Cars]

Hello! I need help of a serious nerd. I live on a computer. I started programming with I was 10. I've been doing pc gaming since like 7 or 8 with club penguin. I do several freelance services based around computers. This problem is a different thing for me. I've never had this is my 7, 8, maybe 9 years on a computer.

I've been working in Pro Tools, a digital audio workstation aka the things people use to mix and make recorded music sound the way it does. I've been using it for years.

Three days ago, while booting up pro tools, instead of the usual sign-in prompt I got this fun message.

"

I can connect just fine to http://avid.com, and fully use the site with no problems. I havent touched anything with my router or router settings or network settings. This problem is both on my desktop, laptop, and my macbook. HOWEVER, when I bring my laptop over to my friends house, It works fine on his internet. Why is this happening. This is serious as I do this for fun, and I love doing it, and I'm losing clients aka money.

Please help me figure this out.

I'd probably say it's an authentication error.

What steps would I need to work towards a solution?

If it's a website that isn't yours, I'd contact their support team or whoever you work for. If it's yours, and this has never happened before, then I honestly have 0 clue.
