VPN and tailscale blocked on hotel wifi (lemmy.dbzer0.com)

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.

Try mullvad use different ports, use their circumvention approaches.

Use your cell phone mobile data

Talk to the hotel, tell them you cannot connect to your corporate vpn, ask if they have a workaround

I've used mullvad but that can't punch through either no matter what. Unfortunately I don't have enough mobile data abroad to fuel my streaming needs for the entire duration of my trip.

I'll talk to the reception when I get back to the hotel I guess...it's really frustrating and I hate using hotel WiFi without a VPN.

What country are you in? China?

Go to mullvad settings and choose random ports

Try 53, 80, 443 etc

Just Czech republic, I've already tried this in mullvad, it never connects.

It would be absolutely bizarre if you couldn't connect with WireGuard port and Wireguard obfuscation set to Automatic. Things to try first:

Connect without your VPN and try to access a single website like the theguardian.com
Once that's working, enable your VPN and that should do it.
If you still can't get connected, try switching out different countries. Each country listed corresponds to an IP to which your machine will try to connect over a benign port like 443 -- so blocking that sort of traffic would be mad unless the IP is explicitly blocked. Therefore, driving to different country targets offers a different IP every time. They'd have to know Mulvad's whole list and block them all.

If the above somehow doesn't work, Mulvad offers support through which you can get a temporary Server IP override. You can enter that in the bottom portion of your app's settings.

They probably are likely using DPI

Not OP, but my ISP blocks those :)
