OCPM 2.0RC1 and Chrome error ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY

[filipzahradnik]

Hey guys,

since upgrading to Chrome Version 45.0.2454.85, I cannot connect to OnCommand Performance Manager 2.0RC1. I get the following error:

Server has a weak ephemeral Diffie-Hellman public key

ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY

Connecting using Internet Explorer works fine.

Any suggestions?

I too have this problem

On our Monitoring screens Chrome version - 45.0.2454.82m      Doesnt work

On my desktop - 44.0.2403.155 m    Works OK

My desktop is pending an update to take effect when chrome is restarted. I dare not restart it as I will lose connectivity to OPM.

same issue on our side ocpm and ocum do not work with recent chrome and mozilla release. latest ie works fine

[Markus_Matschi]

I have found a workaround.
Close all Chrome windows.
Start Chrome with the following Chiper blacklist:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --cipher-suite-blacklist=0x0088,0x0087,0x0039,0x0038,0x0044,0x0045,0x0066,0x0032,0x0033,0x0016,0x0013

This LOGJAM issue (CVE-2015-4000) is fixed in OPM 2.0 GA (release date 9/24).

We have the same issue with out OPM servers running 2.0RC1, but not with our OCUM 6.3RC1.

Our OS is Windows7 and browers is chrome Version 45.0.2454.85 m 

When we try with IE OPM 2.0RC1 opens up but it shows these garbage values 

{{filterWidgetController.getNumberOfAppliedFilters() > 0 ? filterWidgetController.getNumberOfAppliedFilters() : 'No'}} filter applied

Attached is the screen shot of the same.

I also have the same issue, and when trying to open OPM 2.0RC1 in IE the only message i see is "Loading ...."

Opened a support case but no one is assigned for that case yet!

GA is released in less than 2 weeks....maybe a lot of these niggles will go then. Certainly the Chrome one is stated as fixed in it.

[filipzahradnik]

Thanks for confirming the fix. Fingers crossed.

Any changes on a release date? Still not able to get the 2.0GA release from the Software Download page? 

[DisplayingName]

9/24/15 or 9/24/16 cuz one of these dates is past...

[ruijuan]

Sorry guys. We have to release together with UM 6.3 GA and the date was moved to 10/15 due to that.

Firefox 40.0 also has this issue.  Anyone have a way to update that browser?  Thanks.

I want to add a piece of additional information that I received from Unified Manager team to those who cannot wait for the OPM 2.0 GA.

- Latest version of chrome (45.0.2431.0 or higher) works 

[sheelnidhig]

I am running on Version 45.0.2454.93 m and still not working!

[ruijuan]

Sorry to hear that. Looks like have to wait for the OPM 2.0 GA.
