Hello both,
Thank you for your responses and apologies for my delay in getting back to you.
I have checked connection from my laptop (via arp and ping, as well as telnet on port 80) and it all seems to be present and correct. I'm using (from Windows) Edge or Chrome 90.0.4430.93, and from my Samsung Galaxy TabA8.0 (my main device I use in the plane) I'm using Samsung Browser v14.0.1.62
I tried the cache clear and just entering 192.168.1.1 (without the protocol prefix) into the browser and sometimes it worked and sometimes it tried doing the redirect. It's like if it fails once, then it always tries the redirect (I guess until I clear the cache again?)
I do feel like this is something to do with the browsers trying to be "too smart" for their own good as opposed to a network issue, but I just wanted to check - and also, I guess if more browsers start to do this, it might become an issue for more PAW users. It is possible to create a self signed certificate in Linux and bind it to port 443 in Apache, but unless it's from a proper signing authority, the browser will still complain!
Kind regards,
Richard
