As part of a test for my studies, I would like to block the authentication page on port 443. I think I made a mistake during the initial installation. I specified "https" for the first time, then I crushed the installation by relaunching ./install, and this time I put "http".
The reason for choosing "HTTP" is because I can't get a valid ssl (I don't know how to get one, it was the school that gave me a fixed WAN IP, and a name domain name, which I can't administer!), even though let's encrypt worked on the specified domain name. When configuring in QR CODE, I get an error downloading the application, and if I put your direct link from your server, it works, but the installation of applications automatically, or messages with pager, does not work more.
Therefore, if I type my domain name on a browser, I arrive in "https", and I can authenticate myself. Except that if I want to generate a QR Code, I go back to "http", and I obviously have to regenerate my cookies.
How could I block access to 443 on the authentication page, without causing the MQTT to malfunction, and the rest? And above all, without having to overwrite the installation again?
Thank you so much.
