If you’re using an Intel-based Mac with Power Nap on, the Private Internet Access (PIA) app may not reconnect automatically after your Mac wakes. Disabling Power Nap can resolve this.
Why Does Power Nap Affect PIA?
Power Nap is a macOS feature available on Intel-based Macs that allows your computer to perform certain background tasks while it's asleep, such as running Time Machine backups and checking for email or iCloud updates.
Because Power Nap changes how macOS manages network activity while your Mac is asleep, PIA may not detect that the network has been restored when the Mac wakes. As a result, the app may not reconnect automatically.
Disable Power Nap on a Mac Laptop
Note: Steps and menu names may vary slightly on different macOS versions.
Select the Apple menu, then select System Settings.
Select Battery in the sidebar.
Select Options.
Open the pop-up menu next to Enable Power Nap and turn it off.
