Cause

This issue has been seen to occur when either:

1. The load balancer is not configured for SSL passthrough. When using SSL termination on the Cloud Director load balancer, the transfer link used to upload the plug-in can not be read by Cloud Director Availability causing the upload to time out. 
2. The load balancer has HTTP security rules in place which may block the plugin installation from being passed though to Cloud Director for installation.

Resolution

This is a known issue affecting Cloud Director Availability 4.x. Currently, there is no resolution.
