I have initially reported a troublesome in the Technical Forum but I haven't receive any real answer yet. I have no trouble joining my own server but I still have difficult joining other people's servers, even when I use the correct build (which is 1.15.2). My question is: Could it be related in the different version of the iwad. What I do have is the original DOS iwads from Ultimate Doom and Doom 2. I do not have the Steam version and I was wondering if the majority of your good people are using the Steam version. It may me wondering why some people can not join my server since I use the original DOS iwads. I do not know if it does make any difference of which version. But it would be nice to know for sure. Thanks.
