Problems Accessing EAA Forums

Getting a weird problem that started about 1.5 weeks ago - I can open the forums and read 2 or 3 threads, but after that, I get a popup saying;

"Hmm. We're having trouble finding that site.
We can't connect to the server at eaaforums.org
If that address is correct, here are three other things you can try:
-try again later.
-Check your network connection.
-If you are connected but behind a firewall, check that Firefox has permission to access the Web."

I come back the next day and things are again normal, but the issue comes up again after accessing 2-3 threads.

I'm running Windows 10 and using Firefox to access (although the problems happens on MS Edge and Google Chrome as well.

Anyone can give me some help with this?

Thanks,
Jeff

It's not just you. It's been happening intermittently all through Airventure.
