I am unable to connect to the Nord VPN website or the Express VPN website because of a security issue with the Firefox Browser and I am unable to bypass the security and go to the site anyway. Here is what the message said: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nordvpn.com because this website requires a secure connection.

What can you do about it?

www.nordvpn.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

How can I connect to these websites?

I need to download a certificate from a device in my networt called secunet Konnektor

https://www.secunet.com/loesungen/einboxkonnektor

on the manual it's written how to do it.

https://www.secunet.com/loesungen/einboxkonnektor#c1607

I suggest to find a manual somewhere in the first link or in google:

chapter 7.4.3

go to chrome (same with edge)

click on the lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

somehow click on the button where you can open a small windows called "certificate".

The "General" tab shows informations about the certificate.

Click on the tab "Details" and click on "Copy file".

The certificate-assitent opens and after clicking on next, you choose DER-coded-binary X.509 (.CER)

Save the file somewhere where you can find it.

I can't do this on firefox

On firefox I can find a lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

when i click on it and then on something else, i can then click on more informations.

a windows opens called "page informations"

under "security" i click on "view certificates" and a new tabs opens called "certificate for konnektor".

but there is no possibilty to download a cer-file. only a pem file and it doesn't really help me.

Once they log off from that remote session, I cannot log into the site & the page just comes up "loading". I'm using both a macbook air & an imac. I can get on other sites in FIrefox; just not this one particular site.

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 few internal web servers that are used to manage networking equipment. These web sites get this error.

"Secure Connection Failed

An error occurred during a connection to XXX. Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid)"

I have added exceptions. did not change the symptom.

If I revert to an older version of FF I have no problems.

Obviously I would like to continue using FF but more and more of the things i do on my internal network are no longer working wth FF. It seems every update breaks something else i used to be able to do.

Getting VERY old and Ive about had it. Please fix this.

On my desktop version of Firefox, the option shown in this screenshot is disabled: http://screencast.com/t/k7YIzNTC9C7. It's not greyed out on my laptop version.

Also, I'm not able to select the "Always Enable" option to always enable notifications from certain websites in my browser on my desktop, but I'm able to do it on my laptop.

Both versions are updated to 36.0.4.

The latest update of Firefox, 37.0.2, will no longer work with our ERP system. It tell us:

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

But our site does in fact have a valid Go-Daddy certificate. Even though this site is internal and behind our firewall and not visible to the outside world we choose to connect using SSL. Internet Explorer shows the certificate chain and also shows:

This certificate is OK.

I use to like Firefox better than IE but now I think the best course of action is to remove Firefox and never use it again. I do not need to deal with this kind of garbage.

Unable to get add ons if trust disabled for DigiCert Global Root CA

At some point I disabled trust for this cert (along with many others - I distrust non-English CAs and those known to have been hacked). Then when I clicked "Get Add ons" I would get a failure connecting to services.addons.mozilla.org due to untrusted issuer. There is no option to "add exception" because the site uses HSTS, according to the msg.

Outside of Firefox i had to use my own code to connect to services.addons.mozilla.org and debug the SSL/TLS handshake. I saw the root CA from the server and checked my Firefox trust store. Once I re-enabled trust for the DigiCert Global Root CA, I could successfully execute "Get Add ons".

The point here is that you error screen is not helpful. Even if you do not want to let me add an exception, you should at least give me a clear option to view the cert chain. Otherwise how else can someone possibly fix this? Luckily I work with security stuff so could find the certs in the chain externally by other means.

Thank you.

In the certificates tab - at least that's where I think it is - the is a check mark in the box with title in the question above. I want to uncheck that box, but when I click on it nothing happens. This check of current valid certificates prevents me from going to too many websites that I know and trust - and which I can reach without any difficulty using Internet Explorer. If Firefox continues to give me this trouble I will have no choice but to give up on Firefox as my browser, which would be a shame since I have been using Firefox exclusively for at least 10 years now.

This started July 4th. Unable to access my bank account login page, with either the bookmarked page I have used for years or entering IP address for direct log in to site . I have refreshed. Same problem I called the bank, they had me try Explorer, and it logged in without a problem, so did Chrome. No problem with other browsers. I get a Security Connection Failed page instead of the bank log in page. I have on occasion been able to goggle the bank and log on with Firefox, but not usually. This is the page that pops up instead of the bank log in page. Secure Connection Failed The connection to www.bankofthewest.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.

I do work remotely through an IP address. The certificate has expired but the company does not want it published, so they are not renewing it. I can no longer access this IP address through Firefox because it tells me "Secure connection failed." I can actually get on this IP address if I use IE, but they too tell me it is not safe, but still allow me to get on. How can i get this overwritten so that I can use Firefox (my preferred browser) to do my work?

Thank you

I received a new computer at my office. Installed FireFox, version 39.0, on day 1. No Add-on to start with. HP, elite book, Windows 7 Professional All other websites appear to be fine.

Tried the following, like I have seen on most the 'fixes' for this issue:

Many site issues can be caused by corrupt cookies or cache.

   Clear the Cache and Remove Cookies

Type about:preferences<Enter> in the address bar. Cookies; Select Privacy. Under History, select Firefox will Use Custom Settings. Press the button on the right side called Show Cookies. Use the search bar to look for the site. Note; There may be more than one entry. Remove All of them.

Cache; Select Advanced > Network. Across from Cached Web Content, Press Clear Now.

If there is still a problem, Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

Done all of the previous and nothing works. Yahoo.com still displays down the left side of the page.
