could not connect to management server

Hello,

we are testing BDE 1.0 beta with vSphere 5.5 beta2 and encountered the following problem after a succesfull installation and web client registration:

displayed Error dialogue:Could not connect to vSphere Web Client. Contact your administrator to fix this issue.

We also can't connect from vCenter BDE plugin to Serengeti management server to register the management server with BDE.

We are in an environment where http(s) communication is allowed only through a proxy. Could that raise this issue?

Regards,

daniel
