ssl err_cert_authority_invalid

Hello

I have added our selfsign SSL that we generated from a windows CA server for our district. When I add it to the firewall under the Device Cert and use it for the forward trust I am getting this error

ssl err_cert_authority_invalid

I am not sure what could be causing this error

Unless it is caused by the fact the domain is not listed in the Default Trusted CA in the firewall

Any help would be great

is the selfsigned cert a CA itself, and is the workstation you used part of the domain and aware of the CA?

you may need to import the root cert onto the firewall to have a proper chain available to the client

Yes the self signed is a CA as well

The devices are chromebooks that are enrolled to our district and the cert has been added to the chrome devices via google admin

I have also had my cert signed by an external authority and once that is in place I can not make that a CA or a forward trust

So I am not sure what I am doing wrong

Also when I update a cert in the firwall how long can it take for a device to see that

Thanks again for all your help in advance

@Adami_Longtin,

Can you verify on one of the chromebooks that the cert is acually pushing correctly.

chrome://settings/certificates

Authorities

Should be able to see the cert that you pushed.
