I recently had massive issues reaching my home network from hotel WiFi. I couldn’t connect my regular VPN on their WiFi, I tried a bunch of stuff with different ports, different protocols, nothing seemed to work even for my proton VPN.

I managed to get mullvad running, then I could connect with tailscale (with mullvad VPN still running) and then disable mullvad after tailscale connected. Tailscale then didn’t drop the connection.

Weird work around, but it was consistent.
