ძიება მხარდაჭერაში

ნუ გაებმებით თაღლითების მახეში მხარდაჭერის საიტზე. აქ არასდროს მოგთხოვენ სატელეფონო ნომერზე დარეკვას, შეტყობინების გამოგზავნას ან პირადი მონაცემების გაზიარებას. გთხოვთ, გვაცნობოთ რამე საეჭვოს შემჩნევისას „დარღვევაზე მოხსენების“ მეშვეობით.

ეს თემა დაარქივებულია. დასვით ახალი კითხვა, თუ დახმარება გესაჭიროებათ.

Firefox fails to negotiate TLS on site but other browsers can

Site is https://supportfiles.emc.com

Chrome and Chromium can load it. Firefox on Linux and Windows cannot.

"Secure Connection Failed The connection to the server was reset while the page was loading."

Chrome and Chromium can load it. Firefox on Linux and Windows cannot. I tested with Firefox that has no extensions loaded. I tried it from different networks(thinking that my IP was being blocked).

Wireshark shows that the remote server is resetting the connection.

SSL Labs test ( https://www.ssllabs.com/ssltest/analyze.html?d=supportfiles.emc.com ) shows that NONE of the Firefox browsers they test can open it:

Firefox 31.3.0 ESR / Win 7 Server closed connection Firefox 47 / Win 7 R Server closed connection Firefox 49 / XP SP3 Server closed connection Firefox 62 / Win 7 R Server closed connection

Is Firefox doing TLS negotiation in such a unique way that a remote server can be configured so as to be incompatible only with Firefox?

Using the linked SSL Labs page, you can CLEARLY see that NONE of the exposed ciphers offered by that site are TLS algorithms. The issue IS NOT with firefox, but with the site and the fact that firefox is ACTIVELY preventing insecure and deprecated ciphers to protect you the user.

` Older block ciphers, such as Triple-DES and Blowfish use a block size of 64 bits, whereas AES uses a block size of 128 bits. ` 

Firefox forces a minimal block size of 128 now

and has for some time now. Additionally, there is also this warning text in the warning page that 

states the secondary reason firefox will not load it"

`The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.`
