So, for privacy and security reasons, I use a VPN. This is normally Mullvad (with DAITA and quantum resistance enabled), but I have ProtonVPN, Windscribe, and Orbot handy in case something doesn't work.
However, lately I've noticed my connections being blocked. This is across three different ISPs: Sky, Virgin, and Wifinity. I have tried all three VPNs and Orbot, and I have tried several protocols (WireGuard, OpenVPN, IKEv2, Stealth, and of course SOCKS5) to no avail.
The logical solution would be to use a bridge in Orbot, but the button seems to have been removed. Also, by using Orbot, I will not be protected by my DNS.
I am currently using iOS, but my other machines run Linux and I will be getting a GrapheneOS phone in the near future.
I probably need to switch VPNs. I currently use Surfshark and I experience 2 problems, and I want to see if it's unique to that service.
Lots of sites block my traffic because they detect i'm coming from a VPN. And just not like... banks or streaming services, but stupid things like Autotrader.com. It's silly.
The connection always seems to slow down over time, and I have to disconnect and reconnect to get it working at full speed again. I use it on Linux and on Android and the problem happens across devices.
I use Surfshark as well and have your problem 1, as I assume most VPN users do, but not your problem 2. My connection and speeds seem pretty stable, even allowing me to max out my connection many hours later.
Perhaps the issue is which server you're connecting to.
Yeah DAITA is nice but at a high cost. Quantum resistant tunnels too but not so much.
I noticed that on german reduced cell data I get 0 connection when having DAITA or even just Quantum resistant tunnel activated, so I needed to turn it off.
