#1

Anybody can help me with this? I cant access Udemy using Firefox for few weeks now. It shows this error message.

Your connection is not secure

The owner of www.udemy.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

Anyone knows how to solve the problem other than using other browser?

Check system time, add an exception or the answer you don’t want. :grin:

Edit: Must be you, I can open udemy and log in fine using FF.

Yes i realize it must be my FF has broken somewhere.

System time is correct and i can’t add an exception because it seems FF doesn’t allow me to do.

I kinda reluctant to use other browser, but it seems i have no choice. :sweat:

EDIT:

btw, its funny i can access https://support.udemy.com just fine.

After launching, some kind of refreshing, updating, lots of waiting, I was finally able to check this too…

http://www.udemy.com entered into the browser redirected me automatically to https://www.udemy.com - seems to work ok.

Firefox however appears, for me at least, to be running fairly poorly in contrast to Chrome… more Smouldering Roadkill than Fire Fox… :slight_smile:

I have no problems at all opening Udemy.com which, for me, redirects to Udemy.com/courses/ in my FireFox 52.0.1 (the latest update).
