IE11 Page Can't Be Displayed

  • Problem
  • Updated 3 years ago
I have CE version 5.7.14 on Windows 10.

On this computer, I am unable to use Internet Explorer 11 reliably. When I first open the browser, it goes to the home page (google.com) normally. I can browse to a website or two near the beginning when I first open the browser, but within a minute or less normally, IE11 just starts showing, "This page can't be displayed." It doesn't matter what address I type into the address bar at that point - they all fail. I have to close the browser completely, then reopen it, just to get a site to load again, but it fails almost immediately again. I can't be sure, of course, that this is caused by CE, but I know all network traffic runs thru CE, and I know CE has a plugin in IE (which does show as enabled in the Addons section of IE). How can we figure out if it's caused by CE or not? Thanks.

Hi John,

I apologize for our late response and for the issue you're experiencing with Internet Explorer. Covenant Eyes has been known to have some issues with other extensions in Internet Explorer, which could be what is causing your current problem. Do you have any other browsers, like Firefox or Google Chrome that you could test to see if the problem happens in those browsers as well? Testing other browsers would be my first suggestion to see if it's an isolated Internet Explorer issue or if it's across all browsers.

If this suggestion doesn't help, you can always call our toll free Customer Support at 877.479.1119

Best regards,
Annelise

No problem, thank you for the response. I have Chrome, Firefox, IE11, and of course Edge (since I have Windows 10). IE11 is the only browser that does this. Firefox and Chrome work normally. I don't have any other major addons installed in IE, other than LastPass, Java, and Adobe Reader, that I can remember offhand. And of course the CE addon.

IE 11 is still not working. It seems I can browse to 1-2 websites, then I get the Page Cannot Be Displayed error every time afterward, no matter what website I type in. This is important because I need to use IE to test websites, so can I please get some help? Thanks.

@Annelise or other CE employee,

Still haven't heard back from any CE employee in almost a month as to my updates on this bug.

Another update: I waited until today to try IE11 again, so today I opened it up and reset IE. I don't know if something else was fixed with the browser or with CE or if the IE reset fixed it, but I am now able to browse the Internet with IE11.

The problem remaining is that I cannot use Developer Tools on any local website. When I access a local site like http://localhost:81 and open Dev Tools with F12, IE11 shows the Tools window for about 2 seconds, then I see a green play button appear next to the Network tab, and IE11 crashes (when I click to Debug the error, it says "An unhandled win32 exception occured in iexplore.exe"). It appears that as IE11 is trying to load the network requests into the Network tab for a local site, it experiences a bug and just crashes. I can successfully load Dev Tools for any other website that isn't local.

I disabled all add-ons to make sure none of them were interfering with IE11. I can't disable the CE addon, of course, so that's the only one I figure could be causing this bug.

FYI, this same IE11 crashing occurs on two completely separate computers, but both have CE installed.

Hi John,

I'm one of the Windows client developers here at Covenant Eyes and I've tried to reproduce your issue with localhost sites on IE11 but so far have been unsuccessful.
I'm using a Windows 10 virtual machine and I can get to localhost sites and use developer tools (F12) just fine (network tab loads fine too).
Specifically, I can use developer tools on the Covenant Eyes dashboard (http://localhost:48867/) and also using a local install of XAMPP.

Can you try going to the Covenant Eyes dashboard site and see if the developer tools load on IE11?
Also, can you give us any more specifics on the local host site you're having trouble loading?

Thanks,
Jared

Like normal, I ran IE11, accessed http://localhost:48867/ , and opened up Dev Tools. It worked normally. I immediately opened up my solution, ran it, and browsed to that address in IE11. This time, Dev Tools did not crash. What in the world?! Like I said, this crashing has occurred regularly on two separate computers, but it has totally fixed itself ATM with this one. I'll have to test the other tomorrow.

Looks like this is another situation like taking your car to the mechanic, and everything starts working normally there. Sigh. :)

John,
I'm sorry for the delay! I know that's frustrating. I looked through the Get Sat posts on Friday, and I thought we'd responded to all of the outstanding threads. Clearly I missed yours.

Your questions here are Windows-specific enough that I don't know the answer straight away. I pinged our Windows Development manager on this, and I expect you should see a response on Monday. 

Thanks for your continued involvement on the forum. We appreciate your participation.

No problem, Patrick. As a developer myself, I understand it takes time to address issues, but just want to make sure Support is at least aware of the issue, just in case it truly is a problem with CE. Thank you.

Hi John,

I met with the development team this morning and talked about this issue.  One of our Sr. Developers is going to investigate.  I'll keep you posted on his progress.

Thanks,

@Shawn, any updates?

I am now using CE 6.0.16, and the problem is still occurring. I enabled IE's application compatibility logging to see if I could get access to any errors being generated in IE11. Whenever this problem occurs, I am seeing the following Event IDs logged:
It appears that a bunch (probably a hundred or so) of 1037 events are logged at first, all within a second or two, then it logs a 1047 and sometimes a 1021 at the end. Click the links above to read about each event.

Under the "Example" section for the 1037 event, I noticed that extensions that try to write to disk but don't have proper privileges can generate this event. Since CE writes logs to disk while browsing, could that be causing IE to write these error events, then CE blocks IE11 from continuing to browse or something?

Hi John,

Are you referring to your original issue (i.e. unable to browse reliably using IE 11 on Windows 10)? I've been doing some testing but so far IE 11 has been browsing fine for me. 

Do you notice the issue when trying to go to certain websites or does it seem to be random? Anything else you can think of that would help us reproduce the issue would be greatly appreciated.

We do have a newer release available on our website - 7.2.0, please give that a try and see if you get any better results.

Thanks,
Jared Burkeen

Correct. For instance, I just opened IE11, browsed to Google, then clicked on a link to olympic.org. I clicked the News link, then clicked on a topic, and suddenly, IE11 immediately went to a "This page can't be displayed" error page. At this point, I literally cannot open any site. Clicking back shows same error page. Typing in a URL manually shows error. I can close IE11, then reopen it, and I can browse to a few URLs again, but the error will occur soon after.

I opened Fiddler4 and had it running when I opened IE11. All URLs I browsed to appeared until the "This page can't be displayed" error started occurring, then it logged nothing, as if the request literally isn't even going through. That makes me think something suddenly begins intercepting requests from IE11 and doesn't let them out.

Note that I don't have this problem with Firefox or Chrome...only IE11.

I will have to try 7.2.0 later. I will respond here when I am able to do that. Let me know if you all have any suggestions until then. Thank you.

@Jared,

I finally had a chance to look into this further. I uninstalled CE 6.0.16, and after restarting, IE works perfectly. So this problem was surely related to CE or CE's IE addon.

As far as reinstalling CE to see if the IE11 problem is fixed in a newer version, I installed Windows 10 Anniversary update last week, and I see that CE 7.2.0 has some compatibility issue with that? Would you advise that I install 7.2.4 beta instead?

Yes, John, the 7.2.4 beta would be the one you'd want to install. Microsoft began enforcing some new requirements for driver-signing in Windows 10 Anniversary Update.
Version 7.2.4 includes drivers that meet the new Microsoft requirements.

Thanks,
Jared
