I'm travelling for the moment, and usually I just access my home network with tailscale and it has always worked flawlessly. But the hotel I'm staying at apparently blocks VPN connections, I can't use my regular VPN for work on their network either and I've tried obfuscation,different ports etc. nothing seems to work and it never connects.

How can I circumvent this, if at all? I'm staying for several weeks, so this is a pretty bug issue.

Yeah this actually works, but only specifically for openvpn on 443 in TCP mode...anything wireguard is blocked regardless of port.

Yep there's a reason I reached directly for that configuration. WireGuard uses UDP, that's one of the first things that gets blocked.

Turns out that's also the kind of protocol corporate VPNs use, reusing port 443 over TCP. They call those "SSL VPN". They get to weed out all commercial VPNs used to bypass their firewalls as well as most torrent/game activity while still mostly catering to their business guests.
