[horde] Cannot check new server version

[poubeline at free.fr]

Hi All, 


I have a strange behavior when I click on the button 'Check versions' in the Horde Administration page. 


When I click on this button the server normally check for new versions of the different Horde components, but instead I have the 'Could not contact server. Try again later' answer. 
Do anyone have a clue on this and can help me to correct the server check via Horde ? 


In a command prompt fi I do a 'pear upgrade -a -B -c horde' I get the horde components upgraded correctly. 


Thanks for your help.
