safari has problems opening 2 specific websites

If Safari is occasionally unable to open a website, the problem is almost certain to be one or more interest-based advertisements hosted by that site. Those two examples happen to be overrun with them. Both are operated by "Warner Bros. Discovery, Inc" and employ the same advertising partners.

Refer to If Safari on Mac doesn't open a webpage or isn't working as expected - Apple Support.

You might try declining their countless data-collection and social media offers that finance such "free" websites: https://info.evidon.com/pub_info/1212?v=1&nt=0&nw=false

Then explain why those websites work fine for me and apparently millions of other Safari users. You are the ONLY one complaining about the two websites not working with Safari. Let’s hear your answer please.

Ok but your problems with Safari will remain until you address them.

Sorry, but if you do not wish to address your problem I do not understand the reason for your question. Why do none of the Macs I am using at the moment suffer from the same problem?
