How to Fix the Game Client Has Encountered an Error 4049
Blade and Soul’s servers have been having trouble lately because more people are trying to play the game at the same time. A lot of players have also gotten the 4049 error and are looking for ways to fix it.
Here are some things that worked for out team that might help you out. This will help you figure out what to do and what not to do.

Solving Connection Issues
Error 4048 or 4049 usually means that your connection isn’t working right. Because of this, we suggest that you run a ping to see if there are any problems.
To find the ping command, type “ping” [1] into the Windows start menu search box. If you’re losing packets, you might want to restart your router or make sure it’s not getting too hot.
Is Your Computer Powerful Enough to Run the Game?
When you start the game, it first checks your system’s hardware to see if it can handle the requirements of running this game. If your computer doesn’t meet these requirements, it will give you an error message and shut down.
To avoid this, download a third-party program that simulates in-game performance to see if your computer is powerful enough to run this game.

Another possible reason is that the game client has suddenly stopped running. When your computer wakes up from sleep mode, this often happens.
If you don’t completely shut down your game before putting your laptop or desktop into sleep mode, you might keep getting error 4049.
