Firefox for Android Community Forum

I have a LAN Controller which I used to use from more than 7 years. Its small server has a http interface, listening on a specific port, offering the possibility of setting the device and control some other devices through it. This controller is also able to send mail messages in case of some defined inputs, it let me see the rooms temperature, I am/was able to start and close the heating system(s) (powering ON/Off some relays) and some more. I used to have a small shortcut icon on my mobile phone and accessed the above mentioned interface almost daily. Now I am not able do do it, anymore. My mobile phone only opens https URLs. I am able to access the controller interface through Windows and I do not on my mobile phone. When try it, the phone displays: "This site can't provide a secure connection mydomain.....ro sent an invalid response ERR_SSL_PROTOCOL_ERROR" Somebody suggested installing of Mozilla Firefox and get use of its HTTPS-Only Mode facility. I installed the application and HTTPS-Only Mode was Off as default. I tried connecting to the mentioned http URL, but nothing has been solved. I proceeded like here: https://support.mozilla.org/en-US/kb/https-only-mode-firefox-android When I try accessing that http URL it displays: "Secure connection failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem." The single option is a `Try Again` button. Pressing it determines the same return.

Am I doing something wrong? Is it necessary to also make some preliminary settings specifically related to the respective URL? Or something else?

Thanks in advance!

I am developing a PWA, and to test it I installed my app on my mobile phone via firefox for android. However, my service worker was written to never update the cache. I would like to update it to refresh the cache on each load, but every time I install my app, it loads the old cached service worker and files, as if it is still running the old service worker. I have removed the app from my home screen, deleted cookies and cached data via the browser settings, and even uninstalled and reinstalled the firefox for android app alltogether. But when I install the app and open it, it still runs the old version. How can I delete this cached data so firefox fetches the new files?
