Getting "Secured Connection Failed" error message on a website that always worked previously

Displays error: 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.
Site could always be accessed previously and can be accessed using Chrome and IE

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?
It is possible that the website uses a deprecated RC4 cipher suite.

In Firefox 36 you could bypass this, but this is no longer possible in Firefox 37.
This is now a standard and already implemented in Firefox and other browsers will likely follow.

We are receiving a "Secure Connection Failed" error message when using Firefox Version 37.01. What is the remedy?

We have multiple websites that do not launch now as a result of the recent upgrade from Firefox version 36.04 to version 37.01. We received "Secure Connection Failed" error messages which indicate that the connection was interrupted while the page was loading, and that the page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please explain why this is happening, and if a fix will be issued soon by Mozilla, as everything was operating normally prior to the most recent Firefox upgrade. Alternatively, please identify browser settings that can/should be changed in order for Firefox to access these basic Internet sites (that are completely accessible using other browsers such as IE and Google Chrome). Thank you.

FYI, I work with the original poster. I looked at the suggestions on that page but none were the issue. Then I found this thread:

And that appears to be the problem we and others are having.

I keep getting a connection failed error message from mail every time my computer goes to sleep, is shut down and/or I change network connections?

Mail mail was working fine for months but now I keep getting an error message every time my computer shuts down or even goes to sleep. I get the exclamation point error and when I try to reconnect it always falis. My internet connection is fine and nothing else is losing connections. The only way to fix it is to shut down mail completely and restart which fixes the connection every time, but it's getting really frustrating have to constantly shut down mail and restart it just to use my email.

Bump ???

Get Secure Connection Failed- Error code: ssl_error_unsafe_negotiation-signing into ebay & halifax bank using 3.6 and tried suggestions posted here.Advised by sites to contact Firefox tech help.?

Further details on Error message include:
# The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
# Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
I can get ebay site up but cannot sign in to my personal account
I cannot even get halifax site up
I have already reported 'broken site'
These sites give no bother when using IE but Firefox is my preferred browser (for now anyway)

And how are you spawning the php instances? I don't see that in the daemons array anywhere.
EDIT: It looks like the info in that page is no longer using pre-spawned instances, but lighttpd adaptive-spawn. The documentation has been made inconsistent it looks like.
You will note that with pre-spawned information, the config looks different[1].
You need to do one or the other, not both (eg. choose adaptive-spawn, or pre-spawn..not both).

Secure Connection Failed (Error code: sec_error_ca_cert_invalid)

Hello
I'm having troulbes accessing HP iLO with FF 36.0 on Ubuntu 14.04 LTS, getting the following error message:
====================================
Secure Connection Failed
An error occurred during a connection to 172.25.X.X. Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid)
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.
====================================
It seems to work with other browser such as Chromium, so the problem seems to be FF 36.0. Unfortunately, I don't have an "Add exception" button in FF that would allow me to bypass this warning.
I've already followed the following links:
https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message
https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems
But I didn't managed to get it work. Any idea how to get it fixed?

I have a better answer, upgrade to version 37 via bug 1138332

On attempting to connect to my router's configuration interface, I get Secure Connection Failed

When connecting to my local router's configuraton webpage, I get a "Secure Connection Failed" Error message. "The page you are trying to view can not be shown because the authenticity of the received data could not be verified." No SSL error is shown, so I am unable to track it further. I just did a full distribution upgrade but it appears that Seamonkey also exhibits this behavior as well. Restarting safe mode did nothing, so I am at a loss.

Sounds that your router doesn't send a full certificate chain that ends with a Firefox built-in root certificate.
Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button and inspect the certificate and check who is the issuer.
You can see more Details like intermediate certificates that are used in the Details pane.

I get a "Secure Connection Failed" error with google stating "certificate contains the same serial number"

When I click on a link for a google search, I get the "Secure Connection Failed" error in Firefox. It states, "Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority."
I have followed the instructions here:
https://support.mozilla.org/en-US/kb/Certificate%20contains%20the%20same%20serial%20number%20as%20another%20certificate
and looked at this article:
https://support.mozilla.org/en-US/questions/1028103?esab=a&as=aaq
I have uninstalled and reinstalled Firefox, deleted the entire profiles folder, and reset Firefox. I see that the older (orphaned) article points to my router. However, I have a new router and have updated its software. There is no button to add an exception (as noted in the article), so I can't just bypass it. This problem does not occur with IE, so I have a hard time believing it is my router.
How do I troubleshoot this issue? I really don't want to change browsers.

Here is a screen shot of the error.

Suppress "Connection Failed" Error Messages on Client?

Hi there,
I have a Leopard server which is Managing Preferences for users in groups. In my Login Preference for a group, I have it basically "auto mounting" shares, such as smb://leopard-server/accounting and smb://leopard-server/graphics.
The works great so far. A user logs into their machine, managed prefs determines their group membership, and poof all the appropriate network drives show up on their desktop.
Problem is - when a user is off the network (for instance, at home with their laptop), after they power up and login they are immediately assailed with error messages, one for each failed connection to a network drive: "Connection failed. The server may not exist or it is not operational at this time".
Now it is understandable why Leopard is bringing up those error messages - it's trying it's best to connect to the network drive but the user isn't on the network.
Question is: is there any way to suppress these error messages and let the users who are off-network boot to their desktop "quietly"?
I know you can hold the Option key at login in order to turn off Managed Prefs altogether, but the problem with that is users tend to forget to turn Managed Prefs back on when they get back into the office.
Any ideas?

It's not just you, I am seeing this behaviour too.
Where 10.4 clients would fail silently, 10.5 is throwing the "Connection Failed" error message as you described.
I agree it is confusing to end users and would like a way to supress it, the only thing that springs to mind is manually mounting the share via a login hook that first checks network availability rather than using a WGM configured mount. Trouble is, to mount an afp share with the users credentials via a script is a whole new problem in itself.

In Firefox version 37.0 getting Secure Connection Failed config parameter version.fallback-limit set to 3. Does this support TLS 1.0 .

In FF 37.0 getting secure connection failed connecting to a website. Works fine in previous version. Config parameter version.fallback-limit default setting is 3. In previous version the default setting was 1. Does the setting version.fallback-limit to 3 mean only TLS1.2 is supported. Any help is appreciated.
Secure Connection Failed
The connection to xxxx.xxx.com 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.
Thx,

The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases or may be using a deprecated cipher suite.
You can open the <b>about:config</b> page via the location/address bar and use its search bar to locate this pref:
*security.tls.insecure_fallback_hosts
You can double-click the line to modify the pref and add the domain (full domain) to this pref.
If there are already websites (domains) in this list then add a comma and the new domain (no spaces).
You should only see domains separated by a comma in the value column.

It means your file is too large to fit on a single layer disk.
Recompress to keep the overall size (audio,video and menus) below 4.5GB

Hi Guys, I have completely lost access to Gmail and all Google accounts via Firefox - error message "secure connection failed Error code: sec_error_bad_der

Many thanks for your help.

What is wrong when I keep getting "Secure Connection Failed" message?

Why am I getting the msg "Secure Connection Failed" on most sites I used to be able to access before power outage?

Rename (or delete) secmod.db (secmod.db.old) and maybe also cert8.db (cert8.db.old) in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case there is a problem with the files.
The file ''cert8.db'' stores your user certificates, so if you have user certificates then you may want to export them now and import them after having removed cert8.db.
See Tools > Options > Advanced > Encryption: Certificates: View Certificates
If that works then you can delete the renamed files or undo the changes if you want to revert the process.
