Hi There

At a customer site people are contactig me with a certificate error from google.
If they try to reach google they get a message, that the certificate is not trusted.

I checked the System time on the PC (affected are around 30 Clients) and everything seems to be correct.
I tried also to deactivate the Anti Virus and the Friewall,

Has anyone another idea for this problem??

Cheers
Tobias

It wouldn't be a firewall or anti-virus software issue, so turn those back on  ;-)

A few things you can try:

1. Try clearing the user's browser cache and reset their settings

2. Make sure the computers are not infected with a virus or spyware

3. Run Windows Update and see if there are any 'Root Certificate Updates'. (It may appear under 'Suggested Updates' rather than Critical Updates.

4. If they go to Google using a different browser, do they still get the error?

Thanks for the Feedback.

I've allready reset the browser and tried to open google with chrome and Internet Explorer -> Same issue. There are no viruses on the PC. Computer is up to date with windows updates.

Any Other ideas?

If you view the certificate details, does it say it is google? or does it show a different domain?

hmmm ... what if you go to http://www.digicert.com/help/ and enter the exact URL you are going to ... does it come back as valid?

(From my computer, I entered "www.google.ch" and it came back all clear. Just curious if it returns anything on your end)

the test on digicert came back all clear.

I've checked again with another Anti Virus -> One found but same issue after that.

Hi there

The problem was on the internet provider side.
The internet router was administrated by the provider.
They changed something in the Content Filter and so the certificate error appeard.

Problem solved.
Thanks anyway for the help.

Cheers
