jrCore_load_url error
Using Jamroom
Appears to be your site trying to get an update from the MARKETPLACE and attempting to contact the marketplace module delivery system here on jamroom.net but something in between your server and ours is blocking the access.
Your server is continuing to try to access for as long as it is allowed to wait. It waits, it waits, it waits, then it gives up after 6 minutes.
Guessing your server may not allow curl or other??? check the System Check tool at
ACP -> MODULES -> CORE -> SYSTEM CORE -> TOOLS -> SYSTEM CHECK
--edit--
actually code 200 is OK so it may be that you have a slow connection from your server where its taking more than 6 minutes to download the core perhaps.
