Hi   !

www.edf-feph.org loads just fine for me, so let's try this :

Clear the cache and cookies only from websites that cause problems.

Clear the Cache:

3-bar menu => Options => Advanced => Network => Cached Web Content :
"Clear Now"

Remove Cookies from sites causing problems:

3-bar menu => Options => Privacy => Cookies : "Show Cookies"

Will it load now  ?

Still not loading on any browser including Firefox. All other sites load.

I did a full clean

Any other ideas

I meant all other sites also don't load this website.

I can load it on my samsung phone using the same internet connection

Since this affects all your browsers, there may be a system level block in a firewall, hosts file, parental control program, etc. If you use a proxy server or private VPN, that would be another source of potential inability to reach a website.

Can you access the website if you use Google Translate with a random source language?

Did you try to reset (power off/on) the router?

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
