Website wont be displayed because the authenticity of the received data could not be verified.
I've been having this error for a long time. (error message) Secure Connection Failed
The connection to sys.4chan.org was interrupted while the page was loading.
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.
I've paused my anti-virus, and I reinstalled firefox, and deleted my profile. I used to be able to access this website fine. I haven't meddled with about:config either. I'm stumped, I'm out of options, the website displays fine on other browsers. I'm assuming this error is occurring because the website uses https, but bing works fine. I've disabled extensions as well.

Its because the website does not display ownership information. See if there is a difference if you click on the lock icon in the url bar
Thanks for your reply.
Clicking on the icon just gives me information about permissions(It does not have any) and an option for more information. Is there anyway I can bypass this, such as white listing this website?
I believe so, however I do not know what security flag its having. https://support.mozilla.org/en-US/questions/1058856 that was an older solution for the wrong tls encryption.
I do not know why it works on mine also. Does this happen in a new profile?
Hi matini, when I visit https://www.4chan.org/ and inspect the certificate, it indicates that it is valid for:
- ssl329249.cloudflaressl.com
- *.4chan.org
- 4chan.org
and that it was issued on January 3, 2016. So it should work if your Firefox is connecting directly (not through a filter or proxy) and nothing is blocking the CloudFlare content distribution service.
Since you have Kaspersky, its SSL filtering feature would be a suspect, but usually we see users reporting that no HTTPS sites will load until you set up Firefox to work with Kaspersky (or Kaspersky sets up Firefox automatically). It's not usually a problem with just one secure site with all others connecting normally. Hmm...

Hi, thank you for your reply. I disabled kaspersky from scanning encrypted ports. It seems to have fixed the issue. I don't know why kaspersky was blocking firefox in this manner, as it didn't do this to any other browser. I've had issues with kaspersky being overly vigilant before, but pausing protection usually fixed it.
Thank you all for your help!.
Usually Kaspersky inserts its signing certificate into Firefox automatically, but if you use Firefox's Refresh feature, or lose your cert8.db file, that will break the trust and Firefox will need to be set up to trust Kaspersky again. Perhaps something happened along those lines???

It appears that kaspersky never installed its custom certificate.
