I have Proton VPN and qbittorrent running on Windows 10 with qbittorrent bound to Proton interface.
Every now and then Proton will reconnect in the background which means the port changes and the IP address changes.
How can I monitor Proton for these changes and either a.) update qbittorrent or b.) use Pushover to notify me that a change has occurred?

Can confirm that this happens on mobile (installed via F-Droid on GrapheneOS). It will seemingly change countries or profiles mid day or overnight without a restart.
It is super annoying and causes sites I use to send me through all the verifications again / generate new tokens…
I have not witnessed this on Linux via flatpak but will keep an eye out…

Proton will reconnect in the background which means the port changes and the IP address changes.
That’s weird. What is the reasoning behind that? That would drive me up the wall. A new IP and port would require a new leak test for me. Some VPN slots have a reverse DNS which attaches an identifier to the whole shebang, and in my mind, is unacceptable.
Can I ask, how do you detect that?
Without rDNS:
nslookup xxx.xxx.xxx.xxx (VPN IP)
** server can’t find xxx.xxx.xxx.xxx.in-addr.arpa: NXDOMAIN
With rDNS it might look like this:
nslookup 208.104.203.197
197.203.104.208.in-addr.arpa name = 208-104-203-197.reserved.comporium.net.
ETA: I just pulled 208.104.203.197 out of my firewall. I have beef with them. They hammer me daily from all the way in Gilbert, SC where the fuck that is but I wished they’d stop. I just block their entire CIDR.

If you don’t want to bother with this, something a lot of people do is run qBittorrent with Proton in Docker. There are containers that will pipe any changes directly into qBittorrent. The one I use on my media server is from binhex. All self contained and easy to update since it’s Docker.

Fair warning, my personal machines run linux so I’m not able to test this.
You could use a script like the one listed here to notify you of IP address changes:

Edit: I use something like this with a pushover notification to let me know when my external IP address changes
