#32 CannotSendRequest
When trying to connect to my XenServer, I got the following error message :

I'm running Debian Wheezy and installed first :
sudo apt-get install subversion python-glade2 python-gtk-vnc
I checked on my XenServer are incoming management interface is enable. Also on Windows I can connect to my server when using XenCenter.
I had a similar problem running the latest XenServer version on Ubuntu 13. After doing some debugging with the source code I discovered the problem was caused by the "alerts" list which gets populated as the application starts up. I haven't isolated the exact cause yet, however if you don't mind having the alerts completely disabled you can circumvent the problem by putting a 'return' statement as the very first line in the 'fill_alerts' method of the 'oxcSERVERaddserver' class, which is found in the 'oxcSERVER_addserver.py' file.
