Access to a web application for certain users (not all), at certain times (not always) results in the following error
In IE:
This page can’t be displayed Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in
Advanced settings and try connecting to https://SITEADDRESS again. If
this error persists, it is possible that this site uses an unsupported
protocol or cipher suite such as RC4 (link for the details), which is
not considered secure. Please contact your site administrator.
In Chrome, I get a ERR_CONNECTION_RESET
F12> Network tab shows no activity when trying to access the site.
Any ideas on what might be the issue and how to address it. The web application is built on Angularjs and is running on IIS
The issue in this case was the gateway that we were using for our VPN to Microsoft Azure. Upgraded that to Express Route and the issue went away

I am trying to use ngMap in my application but it gives this error on internet explorer 11:
"0x80070005 - JavaScript runtime error: Access is denied."
But it works in google chrome without any errors. How can I fix this error?
Found this on Microsoft support docs:
"You may receive an "Access Denied" or a "Permission Denied" scripting
error message when you browse a secure Web site that contains multiple
frames"
CAUSE
This issue occurs because Internet Explorer does not correctly
evaluate Internet security zones before it finishes processing the
.pac file. When this occurs, Internet Explorer may assign a URL to an
unexpected zone.
WORKAROUND
To work around this issue, add the Web site that is affected to the
Trusted sites security zone in Internet Explorer. To do this, follow
these steps:
1. Start Internet Explorer.
2. On the Tools menu, click Internet Options.
3. On the Security tab, click Trusted sites, and then click Sites.
4. In the Add this Web site to the zone box, type the URL of the Web site that is affected, and then click Add.
5. Click OK. Note You can also configure Internet Explorer settings by using Group Policy. F
Also, try if this problem persists in other browsers like Chrome and Firefox
I used to have X3D-Edit 3.3 downloaded and working on my Netbeans IDE but I updated my laptop to Windows 10 and some of my files got deleted such as X3D-Edit and when I go onto https://savage.nps.edu/X3D-Edit/X3D-Edit.html, I get
This web page is not available
ERR_CONNECTION_TIMED_OUT
Google Chrome could not load the web page because savage.nps.edu took too long to respond. The website may be down or you may be experiencing issues with your Internet connection.
Check your Internet connection
Check any cables and reboot any routers, modems or other network devices you may be using.
Allow Chrome to access the network in your firewall or antivirus settings.
If it is already listed as a programme that is allowed to access the network, try removing it from the list and adding it again.
If you use a proxy server...
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Chrome menu > Settings > + Show advanced settings > Change proxy settings... > LAN Settings and deselect "Use a proxy server for your LAN".
I've tried that same site on two separate networks and I've tried it with and without a firewall. And I'm still getting the same problem, so I was wondering where I'd get X3D-Edit from?
Happy to announce that upgraded X3D-Edit 4.0 now available

The Application
In short, the application surfaces data from a backend onto a web page. The client application is a Single Page Application made using AngularJS. It calls an ASP.NET Web API service located on a different domain to retrieve the data. I utilize BreezeJS on both the client application and the web service to manage this data. The client is hosted on a SharePoint Online site, and the service is hosted on IIS7.
The Error
I encounter an "Access is Denied" error when AngularJS attempts to make an XMLHttpRequest.open() call targeting this web service. However, though this seems like a simple CORS issue, it has some peculiarities which have me stumped:
Foremost, this error only occurs when using Internet Explorer 11 (or a previous version). When the application is viewed in Chrome or Firefox, it can connect and retrieve data from the service.
The web service is configured to accept the calling origin.
No network traffic is detected either by the native IE development tools or by Fiddler.
Specifically, the line: xhr.open(method, url, true); of the angular.js file throws this error.
Does anyone have any insight as to why this error occurs?
Also, if more specific details are needed I certainly can provide them. I'm not even sure where the issue might be coming from and I don't want to dump tons of irrelevant lines of code.
I think that this is due to using "localHost", i.e when attempting to access a resource in the "Local intranet" zone from an origin in the "Internet" zone.

This is not just a localhost issue as previously suggested. I have a production AngularJS application that is trying to POST to a public Web API 2 on a different domain. IE11, Chrome, and Firefox work without a hitch when the site is accessed externally. When accessing from a subnet that can talk directly to those servers, I get Access Denied and IE doesn't even send the request (Chrome and Firefox work flawlessly, of course. One workaround (I refuse to call this a fix) is to add the site as a Trusted Site in IE11. Even when the security settings for Internet mirror the settings for Trusted Site, I get access denied. I have to add the site on each internal IE system to gain access.
We've got an Angular app that uses Auth0 for SSO login. We primarily use Macs and develop and test locally using the localhost web server. Browsing the site locally using browsers on Mac works fine. We can authenticate and the subsequent redirect does the right thing. The problem is browsing with IE. We can connect to the localhost web server on OS X using the IP address. We had to edit the Windows hosts file to map the Mac's IP address to localhost due to our app using full URLs/URIs as primary keys, so that the keys match.
When I browse the site using IE11 on Parallels, login using Auth0, it looks to authenticate just fine, but afterwards, we get an error when it tries to redirect:
XMLHttpRequest for https://mindjet.auth0.com/tokeninfo? required Cross Origin Resource Sharing (CORS).
Auth0 does have a field for specifying allowed CORS origins, and I tried every conceivable URL that our app exposes, even just *. But nothing worked. In our Angular app, I've tried setting $httpProvider.defaults.useXDomain = true; That didn't work either. I'm new to the CORS concept, so any insights would be greatly appreciated. We just want to find a way to test with IE without having to deploy to a dev server.
Our main issue that we couldn't test with IE11 seems to have been resolved by updating our auth0-angular and auth0-widget libraries to the latest version. I still occasionally see warnings about CORS issues in the console, but we are able to login and get redirected to the correct part of our app.
OK, this used to work, but it appears to have stopped working on January 1st.
We have a .NET page that is displaying some data to our internal mobile users. This page is set up with Anonymous Authentication in IIS7. (Windows Server 2008 R2 is the OS of the web server.) When accessing via our intranet, the page displays fine. When attempting to access via our Blackberries, we get the following error message:
"Error: Page cannot be displayed. Please contact your service provider for more details. (1)"
Is this an IIS error, an AT&T issue, or a Blackberry issue? My Director is on my case about it, and I'm not experienced enough in IIS to know of anything else that would cause this functionality...
You should check with your network ops team. I'm guessing that the blackberries are accessing the server from the external intranet (that's just a guess though) ... so have them double check that the domain/ip is accessible externally. That could be why you can access it from in the network.
Or if your blackberries are configured to access the network via VPN, I would double check that connectivity.
Forgot to post the resolution to this.
It turned out to be a Blackberry issue. With the latest OS, RIM combined the internal and external browsers into one browser. Said browser attempts to determine if a given site is an intranet or internet site. Even though the BES (sp?) was set up correctly, our service was still spotty. Some people could enter our intranet homepage address and get the intranet; others got the web squatter site on the internet. Since the page we were trying to access was nested fairly deeply in the directory structure, the web squatters didn't have a page with that name in their site. That's why we were getting the error shown above.
Our resolution - we created a different BES alias to point to our intranet, and rolled that out to all applicable users. Utilizing this, the browser didn't have to determine if we wanted our intranet site or the page on the internet; it correctly displayed the intranet page.
