We are at the mercy of a captive portal as our only internet access. Captive Portal punts everyone out once a day. Login Mode does not seem to work connecting to the Captive Portal.
By "Logging In", we have to click "Agree" on a webpage.
So we tethered an Android phone for failover mode. Me being curious, I enabled a Power Off/Power On schedule on the Wi-Fi thinking that the failover would allow me to Remote in and manually connect to the Captive Portal. That didn't happen. Who knows... maybe when the Wi-Fi comes back on at 05:05 I will be able to remote in. But does Failover only apply when Wi-Fi loses a connection for any other reason than being turned off? Thank you..
How are you trying to remotely log in via cellular?
I expect MultiWAN (MWAN3) to fail over whenever the connection drops or fails to reach internet.
If wifi comes back after disable/enable or wifi off/on you might have to login (or click "accept") in the portal webpage. (Unless portal uses MAC-cookies, to re-authenticate)
Until then login via Remote will not work, if the path remains via the wifi captive portal.
For remote access via mobile network one probably needs an outgoing VPN. (if Mobile is behind one or more NAT). Cloud access via https://www.goodcloud.xyz/#/login can deliver that VPN based access.
Otherwise I see that "Travelmate" is trying to do autologin. packages/net/travelmate/files/README.md at master · openwrt/packages · GitHub
And Travelmate is in the list of plugins with GL.inet. Don't know if it works or includes the portal login part or not. Didn't try it yet.
No, it can't.
it can't ? What can't? I do have SSH and WEB access through goodcloud.xyz
Remote GUI and remote SSH does work quite well
Have not tested yet the SSH-tunnel through Goodcloud. But SSH tunnel works in direct connection, to access whatever uplink IP address, with whatever application (browser etc).
I use Putty on Windows to create SSH tunnel between any PC-local IP port which connects to remote address and port defined in Putty SSH-tunnel.
If Goodcloud does not offer the SSH-tunnel possibility, then maybe "Remote.It" does ... OpenWrt How to Connect Guide
Then have to check again what MWAN3 does when Internet PING tests fail (is uplink portal still reachable, or is it necessary to disable that test for this portal to be reachable? )
Goodcloud does not provide the SSH tunnel feature needed for accessing 3rd party websites like the captive portal, at least not that I would be aware of.
I remotely access the router via goodcloud using the Remote GUI button.
goodcloud showed the device as Offline and had to go onsite and connect laptop to the router via wifi. When I logged in to 192.168.8.1 I was presented with the captive portal welcome page where we press "Agree".
As expected. Problem is that going on-site is not always wanted, and just clicking that Agree button is some interactive thing. People good in scripting, could probably script that action. (Is what they have done in OpenWRT Travelmate)
If not , then you need either a local or remote browser connection. This is possible and quite easy through a SSH tunnel, but unfortunately the Goodcloud SSH does not support a tunnel to be used by the browser.
The Goodcloud SSH and GUI interface could be used to set up an ad hoc VPN tunnel which would allow this browser access to the portal. Not worked out today, so today I do use a VPN to another AP (with a build in web-proxy server) that AP is connected as client to the GL.inet router via its client wifi. Many other combinations are possible (e.g. remote screen to a PC).
We do have SSH through Goodcloud, so some extra software could allow a tunnel in that tunnel. Have been reading about a "poor man" tunnel SSHUTTLE (requires Python), what is supposed to work here over any SSH connection. The other thing would be to add one of those travel routers with Zerotier, or any other VPN or remote access to a client device. (Teams, GoToMyPc, Zoom, Teamviewer, VNC, .... and many others)

EDIT
More options to get interactive browser access to that portal page ...
