Most public wifi block all the ports necessary for VPN except 80 and 443. Even then DPI will stop most VPN protocol right in its track.

I’ve never had reliable VPN working over public wifi/mobile network, unless I roll my own custom protocol that masquerades as HTTP traffic.

Interesting. I'm an ExpressVPN subscriber (maybe I won't be much longer) and haven't had any problem using it on public Wi-Fi networks.

Same here with multiple different VPN providers. Once I get through the TOS screens I can activate the VPN and have no issues. At one hotel chain (rhymes with a moldy British cheese), I have to activate my VPN first since my DNS provider won't resolve their login page.

I've used VPN over literally hundreds of public WiFi...
