I have been using application loader since one year. But for last few months I have problems with the application loader.
When I click on the send button in the Application loader it shows Authenticating with iTunes Store. This authentication step takes around 5 minutes. After that it shows communicating with iTunes Store for around 10-15 mins and then throws up a communication error:
Communication Error. Please use diagnostic mode to check connectivity. You need
to have outbound access to TCP Port 443.
An exception has occurred:Operation timed out. Could not connect to Apple's web
service.
An error occurred while connecting to the transport host https://itmsdav.apple.com:
Operation timed out.
Could not start delivery: all transports failed diagnostics.
I tried googling and many told me there will be firewall/Java issues. I checked that. There is no firewall turned on or any issues with other Java Application. Its just the problem with my Application loader.
I tried uploading the application from my college, and it works there perfectly. But at my home it throws this error always.
The only difference is that In my college I just plug in my ethernet cable and access Internet and at my home its like a ADSL Modem which needs a PPP connection established. I also found out that the Application loader sends out UDP packets.
Will the problem be in my ADSL Modem? Does anybody have similar problems?
Be sure you don't have Charles proxy running as well (or any proxying software). I was bitten by this and took a couple of hours before I figured out it was Charles swallowing all the requests :)
