Firefox giving following error,

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for 192.168.1.100. The certificate is only valid for the following names: anishamsi.lan:6659, 192.168.1.100:6659, 192.168.1.100, anishamsi.lan

I can see the url is there as listed by firefox error itself (verify with screenshot 1), the url is "https://192.168.1.100/api/validateLogin"

please see the screenshot as well. First screenshot is for the error, second is for the certificate returned by the website and as shown by firefox.

What is the error, i have created the certificate correctly. i am sure this is a bug in firefox?? If not!!! how u suggest i fix this i have added following alt names inside my csr. DNS.1 =anishamsi.lan:6659 DNS.2 =192.168.1.100:6659 DNS.3 =192.168.1.100 I have already uploaded the certificate at names screenshot.

Friends,

I'm really, really hoping someone here can help me:

I have tried resetting my preferences to allow access. I can open my site in other browsers without a problem but really need to have clients access it from Firefox as well.

Please, please advise.

Thank you for your help!! Here is the error message:

when trying to access my website Noblittoilandgas.com I get a SECURE CONNECTION FAILED notice, Error Code: SEC_ERROR_REVOKED_CERTIFICATE, how do I fix this issue?

Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Kaspersky support has been assisting but no solutions as yet. Any help from Mozilla is appreciated. This has been going on for 4 days now.

Using FF version 94.0.2 (64-bit) on Windows 10.

I've tried debugging the extension, errors in attachment

Why does this url fail? This is not the first url I have had that failed using Firefox but works on Edge and IE. Most that fail seams to be political. Is there any censuring being done on Firefox? Thank You Jack

Hi, We currently connect to a vendor devices admin page that is inaccessible via Firefox because of the following error "Secure Connection Failed" (Error code: SEC_ERROR_INADEQUATE_KEY_USAGE) and won't present the option to proceed via the "Advanced" option. Long story.... The vendor is aware of the issue and as the configuration page is always accessed internally and uses TLS in some form they do not want to allow us to make any changes to uploading our own certs.

Anyway recently I was made aware of a keyboard shortcut to force firefox to bypass the error screen and force a connection, however I have not been able to find it since on the Shortcut guide for firefox. Can anyone provide me with this shortcut, It will save having to switch between multiple browsers.

Thanks is Advance,

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I am repeatedly getting the SECURE CONNECTION FAILED error only for Google-related sites like Youtube, Gmail and Google search. I've to then close Firefox and immediately open it again to see those sites again.

This is the Error: Secure Connection Failed An error occurred during a connection to www.google.com. SSL peer was not expecting a handshake message it received. Error code: SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT

"Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_ABORTED_ERROR"

FYKI, the problem started occurring in November, 2021. It had never happened before. I repeat, this error is occuring only for Google-related sites, not for others.

What could be the problem? Please help!

I am getting a Secure Connection Failed error on every website I try to log into on my laptop. The issue is not occurring on my desktop or either of my iOS devices under the same login account. I have tried every "fix" I can find through the FAQ's and through online googling, nothing has worked. I don't have any conflicting apps or security features that I can find. I have tried purging the history/cookies, un-installing and re-installing. After a re-install the websites will work for about 5 minutes then I receive the same Error message. Please help!

from whatever reason can't go to Rockler.com on Firefox - bud can on other browsers?! An error occurred during a connection to www.rockler.com. PR_CONNECT_RESET_ERROR

Hello, I've been unable to access google mail/drive recently, w error code SEC_ERROR_UNKNOWN_ISSUER and certificate issuer CISCO. i don't have any antivirus software, I've tried resetting the proxy, clearing cache, reinstalling Firefox, nothing works. If this continues I'll have to definitely move to another browser - with which I have no problem accessing those sites... Help please? Thanks

Hello,

yes I know that version 3.6.28 is quite outdated now :) What is 20 years comparing to life on earth.. :)

Thing is that I need exactly this version of firefox because only with this version important web project works and now it is impossible to connect to server because I think TLS 1.0 not supported on server any more and old firefox can not handle the new one (do not know for sure, this is my opinion). So now I have very serious problem as I can not use needed web resource and deadline is tomorrow :(

So questions as follows: 1. Is there a way to force to work firefox 3 with web address https://varzybos.bki.lt 2. Maybe I can use non https:// version if all certificates are turned off in some way ?

I tried to add exception, then tried to play with various config option, nothing helped. So at this moment I am desperate.

Thank you so much.

Hello team,

In our website www.beutics.com is facing loading issues in mozilla browser use by computer. there no issues in mobile app & any other browser. can you please help me to fix this issues.

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

   Please contact the website owners to inform them of this problem.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley
