I've been using OpenVPN on my home router running Asuswrt-Merlin for a couple of years now whenever I'm out and about and need to use a public WiFi.
Today I checked in to a hotel in a remote location (no mobile connection) and connected to their free WiFi (no password and no sign on page needed, can browse the internet immediately on connecting to the WiFi), but I get the below error when trying to use the OpenVPN app on my iOS devices (tried two iPhones and one iPad). I know my home router is connected, as I can connect to my home Plex server and stream a film just fine.
I used openvpn perfectly fine a week ago when at the hospital and using their WiFi, so I'm thinking this must be something with the hotel's WiFi?
