After hours of this tonight, I am really frustrated. Suddenly, with no change to my computer, Skype suddenly won't stay connected. I had been online all night and then logged out and back in only to find that I am automatically signed out after about thirty seconds. I stay connected on my iPhone without any interruption, so this only pertains to the Windows Desktop client. I have searched for this problem here and have done all the suggestions: uninstalled and reinstalled, deleted the Skype folder in the App Data folder, signed out of all mobile devices, and turned off my firewall. I really need help with this as soon as possible, as I actually pay for Skype and it is completely useless to me if I cannot stay connected via my computer. Thank you.
