Can't connect to a friends game

[✪ Minami]

2 things
Either when i try to connect i immediately get flashed with a "found server" then "lost connection"
Or it gets stuck on connecting to..

We both tried reinstalling our games
Verify game files
Restarted the server
Disabled firewall
Connecting via ip address

still nothing

My friend can join when i host the server but she be laggin like hell. She gets the "receiving tile data"
I was able to join her server once, idk how i was just able to connect and it was smooth af.

One thing to note if you have a 'Classic Map' you must also have a 'Classic Character' you cant have a Journey Map with a classic character make sure to coordinate the type of map and character with the person you are trying to play with. You will receive the connection lost error for have the wrong types together.

If you simply host a game through the main menu, do this instead.

Today my friend has tried to connect my game and it was frozen on saying "Connection..." and nothing happened. A week ago we have played together via steam (version 1.4) on the same map with the same characters and everything was fine.

I was thinking what if some server configuration files can be the reason? If after I deleted them it fixed a bug, so my friend connected successfully afterwards.

So, what you need to do:

1) Open Terraria stored files on your Documents folder: C:\Users\<username>\Documents\My Games\Terraria (For Windows 10 and Windows 7 path might be different, C - is a system drive by default. If you have you operating system installed on different drive, you should have a look there)

2) On Terraria folder search for next files:

achievements.dat
config.json
favorites.json
input profiles.json
servers.dat

Once you find them just delete it. Do not forget to make a backup just in case if will need these files.

3) Run the game, host the multiplayer game (just as usual, leaves turned on friend access via steam) and wait till you will join the game.

4) Deleted files mentioned above will be created automatically, and it should solve game connection issue. Invite your friend via Steam and hopefully after he try to join the game it will work.
