free/busy info

[NicoiT]

Hi! 
I'm getting this when I try to get the free/busy information using kmail.
I cant find errors in the logs or anything that point's me the problem. Is
there a known problem about this or anybody knows how to sort it?

in Kmail
The software could not upload your free/busy list to the URL
webdavs://user@warp.globant.com@localhost/freebusy/user.vfb. There might be a
problem with the access rights, or you specified an incorrect URL. The system
said: Unknown proxy host webcache.
Please check the URL or contact your system administrator.



in the kmail's debug
