Starting around Jan 1- 2016 some people are experiencing connection issues. The client connects and promptly closes the connection. I don't know what is causing it as I have not done any updates whatsoever. If those who cannot connect can give as much detail as possible about what led up to the issue maybe we can figure it out. Was it after update to Windows 10? Can you connect from another computer that does not have Windows 10? Can you play the off line mode? What Anti Virus are you using? Maybe the firewall is blocking it. We need to find out what is common to those who cannot connect to start to solve the problem.
If I ever get up to speed with a new programming tool I am trying out, GreedyGammon will get a no download browser version That should eliminate most issues. Till then this is all we got and I will do what I can to make it work for everyone.
