@azphillycheese - Welcome to Microsoft Q&A and thanks for reaching out to us.
The error message usually indicates that there is a connectivity issue between the Azure Arc-enabled server and the Azure service.
To resolve this issue, you can try the following steps:
- Check the network connectivity between the Azure Arc-enabled server and the Azure service.
- Check if there are any firewall rules or network security groups that are blocking the traffic between the Azure Arc-enabled server and the Azure service. Ensure that the required ports are open.
- Try installing the Windows Admin Center extension again after waiting for some time. Sometimes, the issue can be temporary and can be resolved by retrying the operation later.
If the issue persists, you can try reinstalling the Azure Arc agent on the server and then try installing the Windows Admin Center extension again.
Hope this helps. and please feel free to reach out if you have any further questions.
