UTM User Portal Certificate Warning

I probably figured out why we are getting this NET::ERR_CERT_WEAK_SIGNATURE_ALGORITH error message. The certificates that the UTM issues are issued to SHA1, but it seems that the complete certification chain must be issued to SHA256.
Where can I change this in the UTM?

Hi RalBlo,

Thank you for the update. 

Run the following command from your UTM as a root to find out WebAdmin certificate details: cc get_object REF_CaSigWebadminCa

Can you provide the screenshot of the error message?  Did you import the certificate from the Management > WebAdmin Settings > HTTPS Certificate? 

Thanks,

The output of the cc get_object REF_CaSigWebadminCa says among other things: Signature Algorithm: sha1WithRSAEncryption.
The certificate has been imported years ago by an external service, but should have been via Management > WebAdmin Settings > HTTPS Certificate.

Here is the screenshot.

you should import a new, trusted certificate from your domain ca.

You mean from our own Windows CA?

yes. User-Portal is a webserver ... so you can create / use a webserver-certificate.

Mostly i use an IIS to create a domain-server certificate and export this from IIS ... the fastest way.

Thank you very much, I will try.
