Here is what I have pieced together. First, I have opened up several tickets with support and I encourage all of you to open a ticket every time you get the error.
• I am behind a corporate firewall & proxy configuration. I have IE 7 & FireFox 3 on both my desktop and laptop.
• I have no issues logging into: MSDN, IBM, Facebook, MySpace, Twitter, ebay, amazon, etc. the list goes on. This is literally the only place I am having issues
• I can login to the iPhone dev center from a sprint wireless adapter on the laptop with no proxy or firewall (not a good thing for a corp laptop, but I did it to validate my hypothesis)
• I cannot login consistently at home, where I have Vista, plus the standard arsenal of firewalls and routers with NAT.
• A little research on the net revealed that there are many more, especially within corporate environments, that are having this issue.
• It appears that there is a process that uses IP address verification (not confirmed, but that would not work well in a proxy/FW corp environement.)
• Tech support provided me with the 1990’s standard fix approach to clear cookies and cache (huh???) if the iPhone dev center needs cookies and cache cleared (for real) then there is something very odd going on with the technology they are using. “1995 called and they want their standard browser fix back”
I am hoping that this can be resolved so that my developers can be productive at work rather than having to get to the dev center through creative and extraordinary means.
