Firefox doesn't let me connect to Unilang

Postby Woods » 2019-11-20, 18:20

Any ideas why Firefox doesn't want to connect me to this website? Everything else works - I've tried with three other browsers from the same PC - two of which are based on Chromium/Blink I think, and one on Apple's WebKit.

Here's what happens when I try to connect:

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to because this web site requires a secure connection.

What can you do about it? has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the web site, and there is nothing you can do to resolve it. You can notify the web site’s administrator about the problem.

If you visit you won't have any problems in Firefox.

The underlying reason is that '' tries to use the encryption certificate that doesn't have a name entry for '' (but only for '' and ''). On that error page, if you click [advanced] you can read the following
Web sites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for The certificate is only valid for the following names:,,,,,,,,,,
