Grails plugin manager not showing plugin list

Hello,

I'm using IntelliJ 8.1.2 an when i open the grails plugin manager on a new created grails project i see  the hibernate 1.1.1 plugin enabled.
Now when i press the "download information about all available grails plugins" button i expected too see a list of all
available grails plugins for grails 1.1.1 but nothing is shown . Should't the not installed but available plugins be listed ?

- after calling plugin-info on a existing plugin i now can see the list of plugins available but can't install none of them resulting always in:

why is this happening and how can i get ariund this without downloading the plugins myself and installing locally ?

Sorry soory for all the noise... somehow a http proxy was set and after disabling it it works great...
Sorry again ..
