I'll recommend this new VPN thing :
Its new so its evolving quickly with weekly releases and nightly builds.
Lots of people have told me about their grievance list due to AI having a big part in the development. It's a bunch of guys in the team, so there's the human element there.
As for my opinion, it's the only VPN I've managed to get working on my own.
I lost connection yesterday and I am not sure what happened but my home computer and my phone were on the same VPN constantly for a week. Jumping from the house WiFi to 5g didn't break the VPN connection but it did take a few seconds the first time I did it.
My other option would be Tailscale.
Update on the lost connection. I had restarted my computer and that changed my firewall device name for the VPN. So it was not rayfish related. It's been pretty steady since.
