Debug HTTPS errors - ssl

When accessing my site, the SSL session is successful while the page loads.
A few seconds after the page loaded FireFox shows that SSL is no longer available.
I am guessing its some script (all I have is Google Analytics and Facebook).
How can I see what caused FireFox (or IE/Chrome) to drop the SSL and why ?

Have you tried firebug? It should show you what is going on.

Vaadin "Cookies Disabled" Message in Chrome

I created a Vaadin (8.2.0) web app in Netbeans and uploaded it on a Glassfish (4.1) server. I can access the app's home page in Edge and Firefox, however in Chrome I get this message:
Cookies disabled
This application requires cookies to function. Please
enable cookies in your browser and click here or press ESC to try
again.
I double checked my chrome settings and know that cookies are allowed. I even added the server specifically in the allowed list.
What do think is missing?
As Artur Signell mentioned in the comments, the solution was to simply clear all the cached cookies in the Chrome web browser. After that, the app just worked fine and I didn't get that error.
I was having the same problem. I noticed that switching to HTTPS lead to these errors not occurring. The same site would throw this error when I accessed it via HTTP, but if I went to the site via HTTPS, then the problem did not occur.

Android manifest simulation over https gives me an error

I've just installed an ssl certificate and the website is now available over https.
On the remote host there is a manifest file for "add to home button" but when I try to simulate it through the Chrome Developer Tools - Application section I get an error saying:
Site cannot be installed: the page is not served from a secure origin
I tried the solution proposed here Why does Chrome keep displaying "Site cannot be installed: the page is not served from a secure origin" in the console? but nothing changed since my setting were already: default.
Have you tried opening the Security panel on the page? It may be able to provide more info. Perhaps it's a mixed content issue (where the page is secure, but it requests insecure resources).

Embedded iframe is prompted for security certificate

Running WAMP and I'm trying to embed an iframe of an external website (mcmaster) in a dokuwiki and I'm getting a security alert that doesn't allow the site to be displayed. Security alert says the sites certificate isn't good, and I didn't get the option to allow the page in the iframe but if i opened in a new window i got the option to. So after allowing it just returns a blank screen. What do I need to enable or exception to add in Apache to allow the server to embed this website? Apologies if this is in the wrong stack but I assume this is a server issue not a coding issue, as other sites work fine with the syntax.

My facebook app isn't loading. ERROR: Operation Timed Out

Some people have asked questions like this, but none of them are answered for some reason, so I am asking again:
I have created a new facebook app and created a basic HTML page, the contents of which are copied from the "authentication" sample on the Facebook developers site. I am always getting an "Operation Timed Out" message in the middle of the canvas (ther other facebook parts are loading perfectly).
I have tried with different URLs, different page contents, and only 1 success - when I loaded the AMAZON.com page in my app :)
My pages work fine when called normally through a browser by the way.
Any idea what I am doing wrong?
Thanks!
Did you specify a secure URL (https) for your app? If you have, is your SSL certificate valid (might have expired)?
SSL support for page tabs has been mandatory since October 1, 2011.
You probably already reviewed this info, but just in case here's the Facebook Page Tab Tutorial with screenshots and step by step setup.

Facebook Connect button not showing up in Safari/Chrome

My implementation of Facebook Connect (just a simple login button, fb:login-button) works perfectly on Firefox and IE.
But the same button is not showing up in Safari/Chrome (Webkit).
Here's what's ironic. In my debugging effort, I saved the page (that contains fb:login-button) up as a static page and then load it in Safari. And the button shows up, everything works!
The exact same page (with the exact same HTML source) rendered by my PHP has no way for bringing up the button.
I'm trying hard to support Webkit here but I'm close to giving up. Can anybody help?
I found one more way this can occur (the blame-myself-for-being-stupid way); it's probably not common, but in the event is saves anyone else the hassle, here it is:
This symptom can also be caused by various security tools blocking facebook resources.
In my case, I'd installed Facebook Disconnect ages ago in Chrome as a plugin and forgotten all about it being installed. I also had a second installation of Chrome that was seemingly identical (but did not have Facebook Disconnect). The first would properly load the fb:login-button, and the other would not; took me ages before I looked at the plugins, because Facebook Disconnect didn't have an icon and so its presence was pretty easy for me to miss.
Here's what you'll see if some sort of security plugin is preventing facebook resources from loading. Just look at the html that renders in the browser using developer tools.
In a normal chrome session you'll end up with something like this:
<fb:login-button><a class="fb_button fb_button_medium"><span class="fb_button_text">Your text here</span></a></fb:login-button>
But in the version with facebook's resources disabled you'll end up with this:
<fb:login-button>Your text here</fb:login-button>
Like I said, pretty obvious in retrospect.
Had the same problem but it was not related to anything like a plugin or malformed content. It seems if you enable country filtering on your facebook page it has an issue with the like button, this should be fairly obvious. Facebook gets your location from your profile and not your IP address.
Make sure to disable country locking if you plan on using the social plugins.
This can be due to having ClickToFlash installed. Either disable it, or check "Automatically load invisible Flash views" in the ClickToFlash settings.
What we found out is that Safari (and maybe some older versions of Chrome or other WebKIT browsers) have a problem with Facebook's code using the innerHTML JS function if your page arrives with an XHTML response header (application/xhtml+xml).
Using text/html solves the issue.
In case of JSF2, which we use, the implementing the fix was as simple as wrapping the FB button like this:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:fb="http://www.facebook.com/2008/fbml"
xmlns:f="http://java.sun.com/jsf/core">
...
<f:view contentType="text/html">
<fb:login-button>Login using Facebook</fb:login-button>
</f:view>
Facebook bug report here:
http://bugs.developers.facebook.net/show_bug.cgi?id=5545
I had this problem with the Facebook button not showing at all and it took me forever to figure out what it was. Luckily after days of hair pulling I will now share the answer with everyone. In my situation I simply didn't have xfbml enabled. In my FB.init I had it set to false:
FB.init({
appId : 'app_id', // App ID
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : false, // parse XFBML
oauth : true // enable OAuth 2.0
});
I changed this to "true" (xfbml) and the login buttons works great now! :P Good luck!
This happened when I had the wrong domain in callback_url in config/facebooker.yml. Apparently it uses that to load the js files.
I had the same problem but I resolved it by making sure the URL in my app settings was exactly the same as the one for my site (i.e. it didn't work when I accessed my site without the www.).
I have tried every suggested solution here and it didn't work for me. But now I finally found the solution.
Facebook requires now a secured (https) for Canvas (Secure Canvas URL). The unsecured one will be deprecated soon.
Here is the main difference, Chrome doesn't like https connections with invalid certifications. On a localhost, it is very likely you have stunnel installed to allow https connection for the localhost. Firefox is ok with the self created SSL certificate and allows you to add an exception when trying to access that site. Chrome doesn't allow it out of the box.
When I load my app in Chrome the page is blank and I dont see any login button.
Click F12 and click the Netwrok tab in Chrome:
You see that the post request to your localhost is cancelled. DOUBLE Click on it.
Now you would see that chrome is blocking the localhost because of the certificate:
click on proceed anyway.
Now to back to your other tab and reload the page:
Chrome works now like Firefox and shows the login button.
