After I followed the instructions and having 15 years of system administration experience. Which I was willing to help but I guess you’d rather quip.

From my perspective unless there’s something that you’ve not yet disclosed, if wireguard can get to the public domain, like a vps, then tailscale would work. Since it’s mechanically doing the same thing, being wireguard with a gui and a vps hosted by tailscale.

If your ISP however is blocking ports and destinations maybe there are factors in play, usually ones that can be overcome. But your answer is to pay for mechanically the same thing. Which is fine, but I suspect there’s a knowledge gap.
