The password management interface is showing multiple resources disconnected:
SDDC Manager 5.2.x
SDDC Manager retained the old credential, which was reapplied, overriding the updated password this caused a password mismatch between vCenter and SDDC Manager, leading to connectivity and authentication issues.
Password remediation was performed in SDDC Manager, restoring connectivity
Note: Ensure all future password changes are performed through SDDC Manager to maintain synchronization.
