Hi Firefox for Android will struggle to load this site as the owner of the site has configured their website improperly. To protect your information from being stolen, Firefox for Android has not connected to this website. When a website you visit attempts to secure communication between your computer and the website, Firefox cross-checks this attempt to ensure that the certificate and the method the website is using are actually secure. Some websites try using out-dated (no longer secure) TLS mechanisms in an attempt to secure your connection. Firefox protects you by preventing navigation to such sites if there is a problem in securely establishing a connection. I recommend that you, contact the owners of the website and ask them to update their TLS version to a version that is still current and still secure. I also notice that you are using a very old version of Firefox for Android. I strongly recommend you follow the guidance in this [https://support.mozilla.org/en-US/kb/update-latest-version-firefox-android article] to make sure you have the latest new features as well as important stability and security fixes.
