DNAC Upgrade failed due to certificate error

netzwerk-mgmt · ‎10-16-2023

Hello,

today I encountered an issue when trying to update our DNA-Center Core Applications.

The error message states " UPGRADE FAILED: Get "https://X.X.X.X:443/api/v1/namespaces/kube-system/configmaps?labelSelector=NAME%!D(MISSING)catalogserver%!C(MISSING)OWNER%!D(MISSING)TILLER": x509: certificate has expired or is not yet valid " (IP-Address was replaced with X's)

I replaced the expired SSL-Certificate for a valid one and tried to perform the update again. Sadly i still receive the error message.

Could anyone assist solving the problem?

Thanks in advance.

Do you have any documentation on where I can restart the required services?
Since the appliance is not business critical, can we simply restart the entire appliance?
If so, would I do that via the CLI ?

>...can we simply restart the entire appliance?
- Probably advisable , my original idea was that it could be due to some (earlier) caching effect ,
