If you connect to the network and open firefox, it will display a toast to open the corresponding captive portals page. You can then login through that. Given that your VPN isn't blocking unencrypted connections etc.

I assume the network advertises a captive portals url and identifies you based on your MAC address.
I do construction work and travel every week. I've had this problem pop up in the last month when I connect to the hotel wifi. I just open Firefox and type in the default gateway IP and then it takes me to the login page. For whatever reason it stopped opening the page for me.
I still cannot connect to captive portals for public WiFis, eg on train or hotel and I have no idea where the config comes from.
DNS? Resolve.conf? Systemd network manager? WTF?
(Probably for the best though, so I use my phone 5G and not these suss open networks )

The config is server-side (router).
I get "limited connection" I think when I try connect or "no internet".
I don't make it to load the portal page...
so maybe I'm not recieving at IP from the network?
