Cannot add vCenter in VMAN when configuring data sources. Always shows the error at Enable Collection Schedules: "<vCenter IP> cannot be connected using the configured credentials. Please validate the credentials and try again." However, the credential is definitely correct for we can log on with it by the vCenter client.
Could any configuration be wrong? vCenter TCP port? The network address? Or on the vCenter side?
SolarWinds Experts, please advice and thanks in advance.
