Incredibly often, it seems that Safari fails to load a website. It happens both on my Mac and iPhone and has been happening for a long time. I think this has to do with my WiFi, but I fail to see anything unusual in my Ubiquiti setup.

Anyone seeing similar issues with Safari, or is this some issue in my Internet setup?

(Yes, I've tried disabling all extensions)

@simonbs I see it from time to time in Safari on macOS and iOS, but also on Arc browser on macOS. The latter shows ERR_NETWORK_CHANGED. I have a feeling it's connected to iCloud Private Relay. Not a big issue anyway, it does not happen too often, and reloading page solves it.
