Azure Arc: expired server certificate; agent disconnected

Question

Azure Arc: expired server certificate; agent disconnected

Gunta Ledina 41

Hi!
I have a machine that is managed by azcmagent. In Azure portal, I can see that it says:

I have tried connecting and disconnecting the agent from the machine itself, but it is still disconnected:

How/where do I renew the certificate? Which certificate is it?

Fixed this issue by disconnecting/uninstalling azcmagent on the machine. What I missed in the beginning - after disconnecting from the machine, Azure Arc resource has to be deleted from Azure (this doesn't delete the server, just the Azure Arc resource for the server), otherwise trying to connect will fail with "resource already exists in Azure". Once the Azure resource was deleted, we were able to connect the machine again.

(not sure why the certificate expired in the first place, will keep an eye on it and if it happens again, will investigate deeper)

Hello Gunta Ledina,

I am facing the same issue now. I have a question, when you say Azure Arc resource has to be deleted from Azure, what do you mean? If I understand you correctly, you mean deleting the server listed in the Azure Arc portal right? But I don't see where I can delete it except when I click into the server. Is that where I am supposed to delete it from? Also, once the resource is deleted, do I then basically making this server Arc enabled from scratch?

Thanks for your help in advance.
