Re: Connection not Private on Chrome

Hi,

Hope you are doing well.

The link what you mentioned was for error NET::ERR_CERT_COMMON_NAME_INVALID.

As per the screenshot attached you are getting ERR_CERT_UNABLE_TO_CHECK_REVOCATION which is different then ERR_CERT_COMMON_NAME_INVALID.

 

Here the revocation check is failing which is done either using CRL or OCSP.

 

This error means we cannot download the CRL or talk to the OCSP responder.  Is this happening for only this particular website?  Is SSL Scanning enabled on MWG for this?

 

Access the website again, in the browser on left hand side you will red symbol with not secure, click on it and see what is the certificate present their and click on the certificate and see the CRL and OCSP details their.

Re: Connection not Private on Chrome

This was seen when users started working remotely, it is only seen on Chrome and not other browsers. These are multiple public sites and not just one :

cnn.com

nbc.com

washingtonpost.com

Just a few for example and yes sorry it is Cert Error.

Re: Connection not Private on Chrome

Hi,

Thanks for the update.

 

How is the traffic being routed here? Is the traffic going via our cloud?

 

Can you create a service request with us and ping me the SR no, so that we can work on this.

 

Regards

 Cloud - I am assuming with this sub agency. There has been a couple of Network changes since almost 60,000 of users are working remotely.

 

Thank you
