Azure Stack HCI Nodes are showing disconnected for Azure Arc.

Please help!

My HCI (v22H2) cluster nodes are showing disconnected in the Azure portal.

Re-registering the HCI cluster didn't help.

"azcmagent check" cmd shoing no connectivity error.

azcmagent show gives following error-

Hi Pankaj Vishwakarma,
Thank you for reaching out to Microsoft Q&A forum.

when you're facing this issue with your HCI nodes showing as disconnected in the Azure portal is related to authentication problems or might be other issue. The error indicates that the certificate used for authentication is either expired or not valid, causing the failure to acquire a token. To resolve this, you should check and update the certificate to ensure it’s valid and not expired. Additionally, verify that the system time on your HCI nodes is correctly synchronized with an NTP server to avoid any time discrepancies. After updating the certificate and checking the time settings, try re-registering the HCI cluster.

For registration issue, please follow this document When tried to opening document it display 404 - Page not found but in that page you can check appropriate document for related to your issue
