I am getting below error when trying to open another https site (with self signed certificate) in IE11.
"Content was blocked because it was not signed by a valid security
certificate. For more information, see “About Certificate Errors” in
Internet Explorer Help."
When using IE9 or IE8, we used to get the same error along with a pop-up message "Show Content" clicking on which will display the content. But IE 11 is not displaying "Show Content" option.
Can you please help in enabling that option for IE11? I researched in SO and lot of other places. The option given was to install the certificate. Is there a way to enable "Show Content" option without going through certificate installation path?
No, you cannot. There is no way to get rid of it without installing the certificate.

I have an application that uses certificates (*.p12) to authenticate users. I want to be able to use it in Microsoft Edge (version 42) and Internet Explorer (version 11), but these browsers give me issues.
Speaking specifically of Edge, I have added the certificates to the certificate store, and they are available for me to login. When I navigate to the website, I get prompted with a window that says "Select a Certificate" (as I expect) and I select the desired user's certificate from the prompts dropdown and click "OK".
This is where the issue occurs. After I select the certificate, the prompt immediately pops back up. The prompt can reappear between 2 and 10 times. It seems to be worse in Internet Explorer. Either way, the re-prompt impacts my ability to do a number of things with the website that I need to do.
Is this a common issue? Is there something that I ought to change in my browser settings in order to prevent it?
Thank you for any help.
I hope you can help me. I searched the whole internet, found loads of different tips and steps of how to do it and nothing works for me.
I build a simple application which has Webbrowser1 embedded. Soon I found that many websites does not display correctly so I found that a regsitry key can be tweeked to make the application to use IE11.
Now I have the issue with HTTPS:// self signed certifcation.
Basically in my Apllication the website displays:
In IE11 browser I get the
Basically if the "go on to the webpage (not recommended)" was in my app I would not have a problem. But instead I have the "Error Code:0".
I tried bypassing this in IE11 internet options > advanced > security
I tried adding the website I am interested to open inside Trusted Sites
I tried to follow steps on the interent for IE11 to simply bypass this security feature
I tried looking for the way to bypass this on VB using
ServicePointManager.ServerCertificateValidationCallback =
New RemoteCertificateValidationCallback(Function() True)
The above line maybe works, but I don't know how to utilize it.
To summarize;
I have webbrowser1, textbox1, button1. When I click on button1 it does webbrowser1.navigate(textbox1.text). It works on every website like a harm except the https with expired certs etc.
What do I need to do to have the possibility to display those https websites?
We've started encountering issues browsing to most https sites.
Examples include: https://technet.microsoft.com/, https://mail.google.com/, https://www.mozilla.org/en-US/firefox/new/, https://stackoverflow.com/
It appears that secure sites that we have visited previously work OK. Examples of these include:
https://banking.westpac.com.au/, https://www.tppwholesale.com.au/login/, https://au.ingrammicro.com/
The errors we receive are:
Chrome: ERR_BAD_SSL_CLIENT_AUTH_CERT
Firefox: SSL_ERROR_ACCESS_DENIED_ALERT
IE11/Edge: No helpful message, but Schannel 36887 errors are logged advising The TLS protocol defined fatal alert code is 49. (These are also logged for Chrome, but not Firefox as it uses the Mozilla NSS encryption library.)
We can prevent the problem by disabling TLS1.1 & TLS1.2 and enabling SSL2 & SSL3. As SSL2/3 have known vulnerabilities we want to resolve this issue properly.
Problem has been observed on Win7, Win8.1, Win10 WS2012R2 machines. It's affecting all our laptop computers except one that hasn't been in the office for over a month.
Extensive googling has failed to yield anything helpful - most SSL connection issues that are discussed seem to focus on the server certificate.
The above errors suggest it being an issue with the client certificate that our browsers are sending to the servers, so I have these questions:
Do SSL2/3 have different client certificate requirements to TLS1.x?
What client certificate do browsers use (we don't have any certificates listed in the user or computer Personal stores)?
I hope there's an SSL/TLS guru out there that can assist!
No need to uninstall ESET. Open ESET > Setup > Internet Protection > edit "Web Access Protection" > expand "Web Protocols" > disable "Enable HTTPS Checking".
It appears that ESET antivirus is the culprit here. Thanks to Nicolas Rey for flagging this on a Chrome forum (refer https://productforums.google.com/forum/#!msg/chrome/WHw6ow1kGUs/MW3gt1hZEQAJ)
The rollback option that Nicolas suggested didn't help, but uninstalling and reinstalling ESET resolved the issue.
In Eset go to advanced setup. Then click WEB AND EMAIL, Expand SSL/TLS. Click on edit in List of known certificates. Change access to allow or remove sites from here.
In Eset no need to Disable "Enable HTTPS Checking" . In Web access Protection click URL Management> Click Edit on address list then add on list of allowed addresses
We are usng Weblogic 8.1 and administration console suddenly stopped and inaccessible today.
For more than a year we use to access it until today as it is being blocked by these browsers:
Internet Explorer -
There is a problem with this website's security certificate. When i click continue, it's not redirecting to the admin console.
Google Chrome - SSL server probably obsolete.
ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION
Firefox - Secure Connection Failed
An error occurred during a connection to 192.168.0.18:17050. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)
You are running a very old version of JRocket Java equivalent to 1.4.
There is a SSL protocol mismatch between your modern browsers and Weblogic's JRocket.
My best guess is to install the JRocket Java Cryptography Extension (JCE) Unlimited Strength files into your JRocket to boost the cipher list.
nmap has a ssl-enum-ciphers that will be able to print out the list of ciphers avialable before and after you install the Unlimited Strength files. See answer.
As an alternative and very ugly solution in Firefox.
Try this.
Enable support for 40-bit RSA encryption in the Firefox Browser:
enter 'about:config' in Browser Address bar
find/select
"security.ssl3.rsa_rc4_40_md5" set boolean to TRUE
Or this.
Open a new tab in Firefox and type “about:config” in the URL bar
You would get a warning dialog box, click Promise to be careful and move on
In the search bar, enter the following security.tls.version
First, right-click on the setting “security.tls.version.fallback-limit” and select modify. You’re going to change the “1” to “0”. Then do the same thing with “security.tls.version.min”, changing the “1” to “0”.
I have an internal website in our company that uses HTTPS and the Server's certificate. The thing is since this certificate is self-signed, when anyone browse to that web site it gives a certificate warning. What I did on my PC I opened the site in IE and then clicked on the certificate error in the address bar and on the general tab clicked on Install certificate, selected Local Machine as the store location and placed it on the Trusted root certification authorities. Using a MMC I also verified that this certificate is installed successfully. But the issue is that the certificate warning is still there!
I was facing the same problem as you before, and i think it is impossible to remove properly the warning even if you use firefox, chrome or you own web browser based on Internet Explorer libs, your company must bye a certificate from companies like verisign. The only way i found to remove the warning message using IE is to trap the window wich warn you using WINAPI (getting window handle by the window title of the warning popup then find the handle of "OK" button and send a message to simulate a press on it)..
You can try adding this to trusted sites in IE. If you have group policy access it can be set for users also.
Open IE
Click Tools and select Internet Options
Click the Security Tab
Select Trusted Sites icon and set the Security level to Medium Low.
Add the site to Trusted Sites by clicking sites button.
Close all the Windows. Then open the browser.
See if that will work for you.
