Windows server 2025 SQL patching cluster problem.
Dear Team, I have a problem when I am patching upgrade windows server 2025 with KB5091157. After patching is the clustering is not able to join back; it shows the error with credentials. The log error is "Cannot connect sqlxxxxxxx." you do not have administrative privileges on the cluster. Contact your network administrator to request access. Note: The server is not in a different VLAN network.
