The Certificate for [domain] couldn't be verified

Hello,

Just to be sure, are you refering to this help topic https://help.remotedesktopmanager.com/kb_security_certificatevalidation.htm ?

Best regards,

Hi Jeff,
yes that's the topic i was referring to. Any idea why RDM comes up with the popup while the certificate is (still) valid?

Hi,

In the certification path tab in the certificate window, what is the certificate status?

Do you see the whole certificate chain?


Best regards

Hi,
thanks for the quick reply.
I see the whole chain, and the certificate status for the whole chain is: This certificate is OK.

Hi,

Do you have an intermediate certificate and is it also installed in the certificate store?

In which store are they installed ( user or local machine )?

Best regards

Hi Mathieu,
Both the Intermediate and the root CA certificate are installed in the windows certificate store.
The root CA certificate is installed in the trusted root Certification Authorities computer store.
The Intermediate certificate is installed in the trusted intermediate certification authorities computer store.

Hi,

Can you export the certificate and verify with it the following PowerShell commands :

To export :
Go in the details tab and click on "Copy To File" then proceed to export the certificate to a .cer file.

Script to verify :

In a PowerShell console first run (replace the path with the path to your certificate):

$cert=New-Object System.Security.Cryptography.X509Certificates.X509Certificate2("C:\Users\mmorrissette\Desktop\cert.cer")

and then run :

Test-Certificate -Cert $cert
Is the script successful?

Best regards

Hi,

I found another tool if the Test-Certificate command isn't available on your powershell version.

certutil -verify "C:\Users\mmorrissette\Desktop\cert.cer"
Best regards
