My guess is that its used instead of transmitting username + password every time, I think linking process sends user+pass and gets back API key which is used for everything "user related".
I have tested DMZ right now, same problem, failed to connect to server ... :S I did everything I could come up, I even thought DNS was cached so I tried Google DNS, tried wired network, also wireless network, but nothing works ...
Yes, but I didn't forward any ports except to one needed for LINK, and Test shows they are good. Can you tell me all the ports I should forward and try again ?
Same here :S
I tried everything ... Changed my password to 12345 - not working, then registered new account - not working, always getting "Failed to connect to server, check your username and password". I'm afraid you broke something by moving the site to new location
I would just like to point out that yesterday everything worked normally, bad things started happening when you switched to new site.
