we are experiencing problems with the following portal only in Internet Explorer: http://maps.rhein-kreis-neuss.de/Geoportal/
Some WMS are loading, while others are not. There are many error messages saying "Request not allowed":
and the services window shows this (fehlgeschlagen = failed) :
The log file on the server shows this:
The developer tools console show this (19 times):
When I reload the WMS, it works:
In Firefox we are not experiencing any of the above problems.
We also have a Test Environment, with the same WMS running on the Test Server, which
The console also shows this (but I think this is unrelated):
Does anyone have similiar problems with IE? Any suggestions what we can do to make the portal run in IE as well?
I hope I gave enough information on this strange error.
It would be great to get some help here.

IE has always been temperamental and we have always suggested using a different browser.
In doing a quick test of your Geospatial Portal, I am not getting any errors if NOT in development mode.
In development mode I do get the occasional error that you are seeing, this leads me to thinking is just another IE11 quirk.
What is the version of the Operating System and IE 11 you are testing with?
What we have found is IE 11 can behave differently depending on the Operating System.
We currently recommend using Chrome, FireFox, and Edge over IE.
Simplifying your Portal to reduce the amount of WMS connections maybe an option to consider.

thanks for your reply. I also favor other browsers over IE, but of course our customer wants the portal to be usable from IE as well since it goes to the public and you can´t control which browser they are using.
How do I turn off development mode? I´ve looked for it pressing F12, but I can´t find a place where to change to or from development mode. I´m not aware that I turned it on at any time.
We (and our customer) are using IE 11. I am using Windows 10, our customer is using Windows 7 and we´re both getting the same errors. Also sometimes the WMS look like they have been loaded in the legend but they don´t show
By simplifying you mean having fewer WMS or simplifying the WMSes itself? Actually both will probably not be an option since our customer would rather publish even more WMS than reducing the amount of WMS.
I found that the DOM Explorer shows this in IE:
This does not show in Edge or Firefox which makes sense, but I´m a bit confused about the IE 9 since I´m working with IE 11. Could this be part of the problem? Or does it just mean that it is compatible with IE 9?
I´m quite lost how to solve this problem

I believe I wasn't specific enough trying to make my point, which is the issue could simply be that IE 11 is buggy and it is impacting the Portal.
I tested again yesterday 2:00 AM MST using your Geospatial Portal and did not see any issue's, nor the X-UA-Compatible Metadata tag,
The only suggestions I can make is:
Hope this helps.

The X-UA-Compatible meta tag is removed from later releases of Geospatial Portal where we introduced a new SVG rendering engine. It's certainly removed in 2018 release and I think it was done retrospectively to 2016 in some of the later EPs although I'm not 100% on that.

Hey Marc and Jan,
thanks again for your replies!
We found that we have an issue with our proxy server configuration so I hope my colleague who is responsible for the proxy server will be able to solve the issue.
I´m still confused about the X-UA-Compatible meta tag but as long as it works with the new proxy settings I´m ok
If the problem persists, I like the option to inform users about the IE limitations.
Thanks again for your support!
