    So recently I've switched back to an old BlackBerry Curve 9300. Everything works quite well, except this one Wi-Fi issue.

    Basically, the browser that comes with the phone is unable to connect to most sites. Sites like https://www.google.com.au and https://www.youtube.com.au load fine, but other sites like https://duckduckgo.com or https://github.com do not load, and display an error "Unable to connect using the current security settings" immediately.

    Despite this, the Opera Mini browser is able to connect to the sites fine, without any error.

    The phone is accessing the internet through Wi-Fi, as I do not have a data plan at the moment.

    I am currently in the process of writing a Java-based application for the phone for my own use, but cannot connect to a site I need to because of this issue.

    The BlackBerry SDK comes with an emulator, and I noticed in the emulator the same issues occur.

    I've gone into a bit more detail in this StackOverflow question here: https://stackoverflow.com/questions/60664702/blackberry-will-not-connect-to-some-webpages-with-https

    I believe this is some kind of certificate-related error also, as the issue seems to not be present if I try to connect using pure HTTP instead of HTTPS. Though this is not a solution as I need to be able to connect securely.

    Any help would very much be appreciated.

    Could be that the browser does not support TLS 1.2, certainly doesn't support TLS 1.3. Even BB10's browser isn't loading pages now because of TLS 1.3 requirements.
