I think this is an Android 12 issue for all Android users, not just /e/. When you restart the phone, you have to go into Settings>Network>VPN and turn off always-on and turn it back on to reestablish a connection.
This sounds like the issue I’ve been having with Proton VPN since the v1.9s upgrade.
I’ve found that by turning off wi-fi a VPN connection is re-established using mobile data which then stays active when I turn wi-fi back on. When not using wi-fi turning mobile data off then back on works for me.
Not a solution but I find doing this from the pull-down menu a quicker work-around. May be worth a try.
just for clarity and You may be aware of that already:
the “inbuilt VPN” means traffic is routed via TOR-network, this “VPN” is due to the Hide My IP-module of eOS`s Advanced Privacy.
That may not exactly equal a paid (or else) VPN-Service as it would be commonly understood.
If you want to use a third-party VPN-service you need to switch off the Hide My IP-feature as there´s only one single interface for VPN in Android (and thus in eOS) that can be used by only one service or app at a time.
And: any service or app that utilizes this interface is considered being a “VPN” from the OS-perspective…
Do you have other apps installed that may have set up “VPN” as well and thus might interfere with AP by also trying to use the VPN-interface?
Have You tried switching off “always on” for the sake of failure analysis?
OK, I understand You do not use the "Hide My IP feature anyways …
In that case do not expect any funtion from the related “VPN” as it does nothing … it is only set up to be available just in case you want to use this specific AP-feature!
Instead make sure it is switched OFF in system settings → network + internet → (expand) → VPN … as the trouble may be that you keep up (“ON”) the VPN (which is only there to allow function of the AP-feature) but switch OFF the AP-feature (which depends on this VPN-setup in system settings)… (is that understandable?)
IF you want to use real VPN instead, You need to get an app (+ service to log in) and the app will set up it´s own “VPN” in system settings …
no worries, this forum is full of people that are happy to help if they can. I know there are some VPN-knowledgeable people around as well.
Try the search function for VPN and don´t get discouraged, it might look complex…
definitely no need for that when it comes to VPN-services… there´s decent services that can be paid simply via e.g. credit card
my two cents: don´t jump on the first VPN-train unless you more or less know what You do. VPN is NOT the all purpose tool …
true, but it is not THAT complicated on the other hand. But as you have learned: it is easy to mix up the “VPN” in system settings with “VPN”- services (tunnel) (and You are not the first one…!)
The “VPN” in system settings is simply a name for the configuration /specific setup of the one single interface that android provides. It allows apps to direct and thus control(!) all internet-traffic through that interface so they can e.g. provide a VPN-tunnel-service.
Every app that wants to achieve something alike requires its own setup in system settings (“VPN”)
Advanced Privacy utilizes that interface to route the traffic trough TOR network in order to hide your real IP.
If you pay a company that provides a “VPN”-service you will have to install some app that will interact with the service “out there” (you will have to log in somehow I presume) and the app will ask permission to set up a “VPN”-configuration in system settings as well - because that´s the only way for it to control the traffic within the phone/OS.
