n the vSphere Client, you see the error Authentication failed, Lifecycle Manager server could not be contacted. The issue does not occur when you use a vCenter Single Sign-On internal account or the default admin account [email protected].

This issue has been fixed in vCenter 7.0 Update 3a.

If you experience similar issues after vCenter was updated to 7.0 Update 3a or a newer version, please contact VMware Support.

Workaround:
To workaround this issue, login using a vCenter Single Sign-On internal account or the default admin account [email protected] to access the LifeCycle Manager.

It has been noted that restarting the vCenter Services may help with this error on versions 7.0 U3a and above.
