Check for updates online not working all of a sudden

freepbx V2.2

online module update was working for me, then… just stopped. I’m sure I must have changed something, but I can’t figure out what.

“Warning: Cannot connect to online repository (mirror.freepbx.org). Online modules are not available.”

wget of http://mirror.freepbx.org/modules-2.2.xml

works fine, from the * system.

any ideas of what to look at?

Thanks
