APM Webtop with RDP strange Behavior

Hi,

 

I have APM 11.4.1 HF2 with full webtop configured with some RDPs. Whe i try to connecto to RDP (java optino not selected)a window open saying "connetcing to server. Please wait." Then i waitt and nothing happens and appears message after some time could not connect to server and window close. During my tests i figured out that if i click again on RDP icon in webtop when i was seeing window saying "Connecting to Server Please Wait ". RDP opens a second window and RDP works.

 

Any suggestions?
