[OnlineSession] Detect session to join does not exist anymore

Development Programming & Scripting

Hello,

In my application users can host sessions (listen server) and then I’m using the Blueprint “Find Session” node to look for LAN sessions which I then display in a server browser. Users can then select an entry from the server browser and join a session (this works well so far).

I’m trying to do some error handling now and I’m stuck on the following case:

(1) User-1 hosts a session

(2) User-2 opens the server browser and finds the sessions of User-1 (the session is now displayed in User-2’s server browser)

(3) User-1 closes his session (Blueprint → DestroySession → Quit)

(4) User-2 then selects the session of User-1 to join (the session shouldn’t exist anymore in my understanding)

(5) Using the “Join Session” Blueprint node, I attempt to connect to the session

Surprisingly, the JoinSession node returns with “On Success” but obviously no level travel happens.

I would like to know if there is a way to detect this case “A session that has previously been created is now closed”.

Bump, same exact issue.
Did you ever find a workaround or solution?

If a player enters an IP to direct connect to for example and makes a typo or the server isn’t up, they sit on connection screen until my timeout activates. Then if they try to join a valid server or single player they are stuck infinitely in a void until the game is restarted.
