Hi,

I’ve an Ignition gateway set up and working correctly, hosted on a server over internet.  
When I access the server in wifi and with a mobile (android 2.2), it is ok. Work correctly. When I want to use 3G, I’ve the following error : ERR\_ACCESS\_DENIED.  
Tried several web browser, same error (standard htc using webkit, dolphin brower).  
Looked for information into the console, nada.

Any idea ?

I think I got it.  
The problem was with the APN (Access Point Name) wich was wrong but don’t know how this went wrong…  
Set it back to the good one and everythink is back to normal.
