No Phone Notifications When Connected to Home Network via Open VPN

dbrits

I have Open VPN installed on my Galaxy S10, running Android 11. I'm using Open VPN to connect to my home network using a VPN server installed on a Raspberry Pi. ( This is the guide I followed: https://pimylifeup.com/raspberry-pi-vpn-server/ ) I'm using No-Ip as my dynamic DNS service, and I've made sure that port forwarding is setup properly. I can successfully connect to my home network and I have internet access, but it kills notifications on my phone. As soon as I disconnect from OpenVPN, I receive a deluge of notifications (Gmail, Outlook, Twitter, etc.). I can connect to other VPN services, like Hide.me VPN, and I receive notifications. Any thoughts on what might be happening and how it can be resolved?

Thanks for sharing. Those fixes didn't work sadly. Plus, when I'm connected directly to my home network, I don't have any issues receiving notifications.

What difference does it make if you use a VPN for those services ?

I have a DNS sinkhole installed on the Pi that blocks all ads, trackers, and other stupid stuff on the home network. I'd like to take advantage of that while away from home.

Then don't blame your problems on your VPN.

It might not be OpenVPN. That's what I'm trying to figure out. I freely admit that I'm not an expert when it comes to networking, which is why I came here to look for an answer. Search results yielded nothing, so I posted. Thanks for the constructive responses though. :roll: I'll be sure to look into some other VPN software.
