my test log:

 

1. try connect to server.

 

2. disconnect from server.

 

3. happen message in l2server window: [usersocket]unknown protocol 250

 

how fix this?

Use system with correct protocol maybe ? 746 in this case ?

Verify your ILext.ini if you is using custom client protection and you don't have clientext.dll else disable it in ilext.ini

But its funny cause they think its dll problem and thats a native c4 exe message. Garuda post was funny with clientex, hahaha, what has to do clientex dll with system protocol ?
