Hey Folks,

iam getting a bit crazy. The Problem iam talking about is in 4.7, 4.8, 4.9. Iam not sure what the Problem is, but
in the Multiplayer Shootout, and also in my Game (similiar way) i still get the Message “Error: Connection Lost” for the Client.

Twitch Youtube MP Shootout:

first of all i checked Forum and Answershub, but it wasn’t really helpful right now. I collected some of the Questions.
Right now iam a bit confused, cause i can’t really surround the problem. Anyway

On my Game i figured out, it could be something with travelling. Cause i can join a Session in PIE and in a Packaged Game on Lan (internet doesn’t really work now).
On My Game (different then MP Shootout) i made a Session Map and Menu + a Session GameMode. In the beginning i used the standart GameMode with the same result. But i think its better to have an own Session GameMode in this case (not 100% sure). Anyway

As soon as i start the game from Server Side (Load Map) the Client gets kicked out.
When the Client goes back to Find Session, i find the Session with 2 Players (Server + Ghost) and can also Join in and then i can play the Games with the real 2 Players (Server+Client and Ghost is somewhere). So connecting, destroy session etc. works fine, expect the travelling i think. someone any ideas? cause in the MP-Shootout, you do not really travel, cause session starts as soon client connect. so the problem isn’t really relevant there.

would be great if someone could help me and the others, who have similiar problem.

ps: in some thread (did not found it agai), someone talks about player controller and travelling. Maybe it helps someone :smiley: could explain, why there is a ghost player on the server, after the game get started and client got kicked out.

i also can make some pictures, but at all its the same way like in the video or in MP-Shootout Example. Online Subsystem is Null btw.

greetz.

Today i fixed the problem with help from eXi. The Client was switchting the states complete wrong. That created my confusion, with traveling and so on.

Main Problem was, i updated my projects to often. Wasn’t a good Idea to update from 4.2 to 4.3 to 4.4. and so on till 4.9.

Solution:
Create a new Project, Migrate everything from the old into the new, setup project settings (controlls, game instance etc.)
and then, my problem was solved.

it was a really strange Problem. I think it made more than 1 problem. Cause my Code was fine (like in MP-Shooutout), but it didn’t worked well. If you can’t find anything in your Code, maybe my Solution helps.

Hard to compare it, but i tried to run an Formular 1 Car from 2015 with wheels from 1998… Works maye bit, but is not made for it :).

another problem i had, i forgot to add the “spacebar” in the Execute Console Command. maybe this helps

and also your Maps should be in Content/Maps not Game/Maps. but iam sure, you ment Content. :slight_smile:

Does not work for me - i migrate the content and configs, but still the same errors occurs after successfully connect & join to the server :
“LoadErrors:Error: Error /Game/Maps/UEDPIE_1_Level_01 : Can’t find file /Game/Maps/UEDPIE_1_Level_01”
