Is Canada being blocked from Venezuelan news? ( edit, we're not )

I wanted to see how Venezuelans were talking about the attack today, so I looked for news from Venezuela. I found a site called telesurenglish.net and it loaded fine at first.

But when I clicked on a link ( https://www.telesurenglish.net/us-military-intervention-in-venezuela/ ), the page gave me a “413 Payload Too Large” error – something I’ve never seen before.

To test it, I opened the same link while using a VPN, and it loaded without any problem. When I turned the VPN off, the error came back.

Can anyone else confirm whether the site only works when you’re connected through a VPN?

Edit: it does work on my cellphone provider, no VPN required. So It appear that my provider is adding stuff to my requests sent to the server? I'm not competent to figure out what tough.
