I am getting this exception when I am working with PPP on my Fez Cobra iii. It works sometimes for a day sometimes longer and then suddenly this starts.
Do I need to close something or what is your suggestion to stop getting this. It is as if I am losing PPP status - I am still connected to the network and have an IP address but this code fails:
req = my request object.
using (var respStream = req.GetRequestStream())
