Ryan Davidson (1151511) | asked May 08 '15, 10:10 a.m.

I've seen a number of queries about this on the forums - none with an acceptable answer or workaround.

We're using RTC v4.0.3 displaying dashboards in the Web Client on Mozilla Firefox v31.0 or Chrome v37.0.2.

Our External Content Widget display as blank on both browsers, regardless of the URL you try to enter (whether internal to the LAN or external on the internet).

The same dashboard works fine in IE8... although we are first asked whether we want to display unsecure content (to which we have to say 'yes'). We are not prompted for this on either Chrome or Firefox.

Questions:

Has any defect been logged for this in the RTC dev stack?

Are you aware of whether this has been addressed / resolved in the past? If so, for which version of RTC?

Any ideas of workarounds or actions that can be taken to try trouble-shoot why the external content is not being displayed?

Many Thanks

RD

Hi Ryan,

I suspect this could be just a browser security setting, rather than a RTC bug.

I have seen security settings in some webpages that will not allow them to be embedded into the "External Content" widget. Also there are some caveats when trying to load non-secure (http) content into RTC, which is secure (https) by default.

My suggestion is to have the Firebug plugin installed in Firefox and then attempt to load the page. If there is any error, you will see an error message in the console:

Thanks for this Alexandre. I displayed the Firefox Web Console and displayed Security notices, and sure enough picked up notification that mixed content was being denied. Further experimentation showed that I could display pages originating from a https address in the External Content widget.

It worked in earlier versions of Firefox and Chrome as they would warn about mixed content and allow you to proceed... as does the IE version I use.

Don't see much that can be done about this on the RTC end as it's the browser that's denying the content.

 But what is the solution if we need to display the external http content inside the widget?

 I have been able to display external content if it is hosted via https.  I am using 6.0.2.

 Work for me too....it works for https....But what about http?


Robert Carter commented May 11 '16, 2:36 p.m.

I don't believe there is an easy solution to connect to external 'http' content.

You could try this FF add-on, which ignores the server's request to deny cross-site loading in a browser:

It worked for me.
