Vcenter Web Console not working in Windows 10

[kscrupa]

Our vcenter admin recently did an upgrade to vsphere 6.5.  Up until now, I had been making do with the Windows Client, but I can't use it anymore.

In Windows 10:

In Chrome,
If I use the vcenter /ui (HTML5), I can log in, and I can launch a remote console (a separate window pops up), but it never authenticates me.  It asks for the password for vcenter, and I use the same password I used to get into the ui URL.  If I use myuserid@vsphere.local instead of userid, same thing.
Using the vcenter /vsphere-client (Flash), I get a blank page after login.

In Edge:
HTML5 site: Same problems as above.
Flash site: Blank window after login. Flash banner on top of page.  "Use Adobe Flash Player" is on, in Edge's Advanced Settings.

In IE11:
HTML5 site: Same problems as above.
Flash site: IE crashes and attempts to reload the page

If I use a Windows 7 pc, I can successfully log in to vcenter and open and authenticate in a remote console (same userid and vm I tried above).

I tried this (https://communities.vmware.com/message/2723105#2723105), but it didn't seem to help.

I have tried re-installing the software you get from "Download Enhanced Authentication Plugin" more than once (and rebooted).

I have installed the certs under our base URL (Download trusted root CA certificates).

Any ideas?

Hello,

Since you have confirmed that the browsers are supporting HTML5, I would suggest we also check for proxy settings if any. Also for reference please see the KB article below with a number of questions around supported browsers around the issue:

Have you installed VMRC on the Windows 10 box? For me there are no problems under Windows 10 (32bit and 64bit). I found it even working on Windows server 2016 (if you install flash player).

Chrome and Edge I havn't tested yet for this pupose, but FF (for the Flash version only ESR 45.9.0 is usable, the later versions are awfully slow) does work, too.

So it is probably a local setting, which is interfering.

I finally got the Flash client working in Chrome.  Even though I had set "Flash=Ask First" in chrome://settings/content , it seemed to start working after clicked "Secure" beside the URL (when I loaded up the page), and explicitly set Flash=Allow.  It was like it wasn't even bothering to display a prompt before.

I also recently did another Windows 10 update to 1703.15063.674.
