My self hosted VPN (outline) on Digital Ocean did not work when I use mobile network

I am in Russia. 2-3 days ago my VPN stopped work with mobile networks. When I am on Wifi everything is fine. What’s the problem? I don’t understand.

Mobile networks in Russia have recently increased VPN blocking initiatives using deep packet inspection filters, similar to what’s seen in China. To bypass these blocks on mobile networks, you’ll likely need to tunnel the VPN through another TLS layer, such as Shadowsocks or stunnel. It’s also possible that your mobile ISP has blocked DigitalOcean (DO) IPs, which is quite common since many people use DO for VPN.

use amnezia app if you don’t have experience with linux, it will configure your server

Thank you. Can you evaluate what does it mean “to tunnel the VPN through another TLS layer”?

I tried amnezia. It works with XRay VPN protocol. Thank you!

Tunneling the VPN through another TLS layer means using a separate encrypted connection, like Shadowsocks or Stunnel, to disguise your VPN traffic. You can set up Shadowsocks or Stunnel on a server, then connect to it before starting your OpenVPN connection. This adds an extra layer of encryption, making it harder for your ISP to detect and block your VPN. It’s also a good idea to have a few different servers/IPs to switch between in case one gets blocked.

xray is not a vpn, it’s a proxy. proper vpn is amneziaWG (based on wireguard) for example

So, proper vpn (amneziaWG) doesn’t work with mobile network
