A short while back I had problems with AdGuard creating a VPN that interfered with the privacy settings in Mail in macOS 12.
All was well. Until this afternoon.
Now, for all messages, Mail out of the blue stopped loading content and displays “Your network preferences prevent content from loading privately”. I have to explicitly tell Mail to load content (images, etc.)
I see no VPNs in Network Preferences.
I have no Proxies configured in Network Preferences.
I have no content blocker installed for Safari.
I know of no other software that might be running a stealth VPN
Even in Safe Mode mail opens this message
Even when I turn off “Protect Mail Activity” in Mail’s preferences the message appears
Nothing new has been installed on the machine since Monterey was installed a few weeks ago.
I’ve begun to have a similar issue. I’m running Ventura 13.1, and I don’t have any extensions installed on Mail. I’ve noticed that if I select “Hide IP address” that the issue comes up, but if I de-select “Hide IP address,” everything loads fine. Would hiding the IP address keep everything from loading? That seems to be a very heavy solution (to block everything), but maybe I’m not understanding the setting.
