Why is my Function not being called on button click?




This is my project but for some reason my join server function is not called when I click the button on my WBP. The debug log always shows:
LogTemp: Warning: Attempting to join a session…
LogTemp: Warning: No session search in progress. Starting a new search…
LogTemp: Warning: Searching for sessions…

And I’m wondering why it is not showing the messages that it should with my function. So the only conclusion I can come to is that the function is not called properly but I don’t know why.
