hello, I have seen in some places in the documentations that you can run a script, command etc when connecting with up but I am not sure if there is something you can execute basically as soon as the user tries to initiate the connection, maybe after checking that there is a server it can talk to but before sending credentials.
the point is that the VPN server is wired to a backend authentication system that will require an login on a web portal, and basically to make stuff easier I would like to add to the config that it just kicks open that site from the get go so it's easier to use as ppl would not need to do that manually.
the apps where this matters are basically openvpn CE on windows, OVPN Connect on Android and MAYBE liunx implementations if they can too. sure the content of what is in there likely needing to be different and maybe one or more cant but worth asking I guess.
