website tug.org does not load

Hi.

I'm unable to access the website tug.org from my Slackware machine (Slackware64 15.0). Firefox, falkon, chromium, lynx, none of them load the website. But, the ping works fine:

Code:$ ping tug.org

rtt min/avg/max/mdev = 231.144/231.501/232.096/0.423 msUsing a livecd (with linux mint) works fine.

I have a laptop with Devuan installed and its fine too.

I have no idea where to lookfor.

Any ideas?

Thanks
