Strange Windows 10 Edge behaviour with HTML5 and domain limited krpano on a Windows 2012 server

Hi, I am back again:

Only on a Windows Server 2012 R2 host, viewing with Windows 10 Edge, I get the "ERROR: Adobe Flashplayer or HTML5 Browser with WebGL support required!" in the following cases:
- domain limited krpano (if I remove domain limit, it works, but WITH the domain limit it works on all other browsers but this Edge)
- html5= anything other than 'always' (so forcing html5 does work)

And if I watch this same project on a Debian/Linux server host, it also works, even in the cases mentioned above.

Is this a known problem? What can I do about it, other than forcing HTML5?

BTW, I see quite a lot of similar problems with HTML5 and Edge, but I haven't seen anything with the domainlimit restriction and I also find it very strange that it DOES work if the Host server is a Linux server, even with domainlimits and html5=prefer...

Cheers!

Thanks for responding Klaus,

That's what I thought, hence the surprise. I will test again, perhaps a one-off.

Tested again, still not working. You were right about the domain restriction though (which was very weird of course).

No problem in the following cases:
* If I use PR3
* If I use Firefox or Chrome on PR4
* If I watch Edge on a Linux Server on PR4 (and PR3 of course)
* If I set HTML5 to 'always'

Not working in Edge in the following case:
* Windows Server 2012 R2, with Edge, with PR4, with HTML5=prefer or anything else than always

So for some reason it detects Edge as non-compliant with WebGL, and if you force it to be (=always) it DOES work.
But PR3 does not have this problem.

I can live with setting it to always, but you said somewhere to only use it in development setup.
If you need to investigate, I can send you the link, but privately please as it is still a testing environment.

BTW, found another thread, where you ask to have a look at:
https://www.khronos.org/registry/webgl/s…xture-npot.html

http://webglfundamentals.org/webgl/webgl…-good-npot.html

The first one passes, the second one doesn't play. So it must be my GPU. Fine enough, I have seen other problems, but why would the same situation work on a Linux server?

Cheers!
