Hi, I've been trying to fix this for about 2 days and I gave up and thought I'd just come here, the problem I've been having is: Every time I try and join a multiplayer through steam It starts saying 'joining _____' then says 'lost connection'. I've tried turning off my antivirus and firewall, reinstalling the game multiple times and a few other things that I can't even remember. I noticed that when I tried validating the integrity of game files, it said 1 file failed to validate and will be reaquired, obviously I checked this first but I tried it again and noticed that it said the exact same thing, apparently I'm always missing one file and steam won't reaquire it even if i re-install the game. Does anyone have any other suggestions or fixes, would be greatly appreciated.

It just happens sometimes and it had been happening even in 1.3 (maybe before as well).
I don't have a straight solution but try these few times each:
- restart host server
- join by host's steam invite
- make sure you and host have good internet connection
- make sure you're 'online' on steam not 'away' or sth

Like I mentioned here: PC - "Connection Lost" Error when trying to join friends multiplayer game when it worked just an hour earlier
I have the same problem. Two days ago my friend could connect to my world via Host & Play, but since yesterday we get the Connection Lost message. We tried the Verify Files method, restarted routers and PCs and even reinstalled Terraria to no effect.

Did you 2 try few times my solutions?

Everything is ok now. Because my friend's terraria wouldn't launch from steam she had renamed her Terraria folder to something else and as a result the game was still on 1.4.0.2 version. After deleting the folder and reinstalling to 1.4.0.3 the problem was solved. To sum up, our problem was that the game was out of date.

Hi, I worked out that I was just being an idiot, I forgot to choose classic instead of journey when making my character.
