I ran into this problem when I updated my connection from a VDSL to a 5G and changed my modem. Everything worked fine before that. Pages like Youtube and Google won't open in Safari, I just get that error message. I looked through the previous threads about this same issue and tried disabling the firewall from both my Macbook Pro 14" and from the 5G router. That didn't help, and neither has anything else I've tried so far.
Ideas?

Hey jojoel,
After changing your internet modem and services, did you follow the recommendations for setting up your Wi-Fi network using this guide: Recommended settings for Wi-Fi routers and access points - Apple Support
Some other reasons this can happen would be due to security software. You did mention disabling your firewalls, but do you use any other security software with your Mac? If so, temporarily disable or remove those applications to see if that resolves this issue. If so, reach out to those app developers to look into this with you: How to contact an app developer - Apple Support
If that's not the case, there are some great steps in the following guide that can help with this issue too: If Safari on Mac doesn't open a webpage or isn’t working as expected - Apple Support
Let us know how it goes.
Take care!
Understood jojoel,
Since this is still happening after reviewing the steps of If Safari on Mac doesn't open a webpage or isn’t working as expected - Apple Support, we'd recommend that you Contact Apple Support so that they can review this directly with you.
Thanks for using Apple Support Communities!
Hey,
I think I've tried all the things listed in those guides. And tried disabling security software too.
On Chrome everything works fine, this just happens on some sites in Safari.
