Custom connector problem with qlik sense desktop 3.1

[#1]

My custom connector broke after installing the new version qlik desktop.

When I try to create a connection I get the error "Invalid Parametres".

I tried old stable builds, the problem remains. I used the debugger, step by step check all the code - the program ends without error and then qlik shows message "Invalid Parametres".

Solved.

There was a problem with connection string. I discovered that connection string should ends with ";"
