Clearpass and Chrome 58

Hi,

Anyone experienced this yet?

 

Since updating to Chrome 58, Clearpass Policy Manager GUI is no longer accessible.  Only top screen header loads. [edit] CPPM version 6.6.5.93247

Developer mode says that dojo.js:16 [Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.

 

On Guard / Guest, and Insight still work however.

 

[edit #2] I found that if you resize the window, the page finishes loading.

I have not seen that in Chrome 58. Best to open up a TAC case.

Ah, thanks for the "resize" hint. I'd opened it in Firefox before I thought of that. We are still on version 6.5.7.85381, so it is not a recent change in CPPM that breaks it.

Just started seeing the same behavior here with Chrome 58. No issues with Firefox 53. Thanks for the workaround.

Yup.  Seems to be a javascript issue.  I couldn't even hit the login button here to post.  Had to disable and reenable javascript on Chrome 58.  Then do the resize trick.

Just a quick update. Engineering is aware of the issue with a change by Google in Chrome 58. I will post updates here.

Thanks for confirming. I was awfully suspicious of the Chrome update.

Hopefully it will be a quick fix. Until then, resize away!

Nothing to report yet. The quick workaround is to briefly resize the browser.

Re: Clearpass and Chrome 58

The issue is found and is supposed to be fixed in the upcoming 6.6.7 ClearPass patch release.

For the time till then, a nice tip I got from Garth Benedict: use the zoom keyboard shortcuts: Ctrl -, Ctrl = to quickly zoom out and in again to get around this issue. I posted a short video demo on Youtube:
