Unable to load UCS Manager 3.1(3b) on IE 11

[dinero]

After upgrading UCS manager from 2.2(6g) to 3.1(3b) we are unable to load the new html5 UCS manager on IE 11. It would just sit at loading forever..

We are able to load/login to UCS Manager 3.1(3b) from Chrome browser successfully. 

Any known issues with HTML5 and IE 11 ??

I am on  IE 11  version: 11.0.9600.18792

Per your comment HTML5 should be supported, but it is not loading the login page , it is just stuck at loading.

Did you only update UCS Manager, or the Fabric Interconnects and IOM as well (which means the infrastructure) ?

Can you ssh on any FI ? what is the cluster state ?

[dinero]

yes, updated the infrastrucuture piece ( UCSM, FI & IOM).

I can ssh to both FI's. , cluster is HA ready.

As I mentioned, I can login to new UCS manager without any issues on chrome browser.

Having issues with IE only.

I have the same issue. Did you resolve the issue?

[dinero]

No. UCSM 3.1(3b)  never loaded for me in IE 11.

I have recently upgraded to UCSM 3.1(3a) and i am seeing slow performance , takes for ever to login and sometimes sessions hang for about 60 seconds, is there a fix for this?

[Vladimir Barmin · Accepted solution]

Check if "compatibility view" is in effect for the the UCSM. Turning it off solved the problem for me.

Also try to decommission and re-acknowledge this worked for me.
