### Summary Hi Epic Games Support, I am unable to launch a UEFN session. Every time I try to start/playtest my island from UEFN, Fortnite opens but then disconnects with this error: “There was a problem” “Network Connection Lost” (errors.com.epicgames.common.processing) In the UEFN log, the session reaches the Valkyrie Beacon connection step, then fails with: UNetConnection::Tick: Connection TIMED OUT FailureType = ConnectionTimeout ValkyrieBeaconClient ConnectionTimeout Failed to connect to beacon Network error occurred when connecting to a server after matchmaking completed This happens again and again when launching the session. Matchmaking seems to complete, but the connection to the server/beacon times out after around 30 seconds. My log shows the failure during ConnectToBeacon / ValkyrieBeaconClient. :contentReference[oaicite:0]{index=0} I already tried: - Restarting UEFN, Fortnite, and Epic Games Launcher - Restarting my PC - Verifying Fortnite files - Verifying UEFN files - Clearing local cache/AppData folders - Trying again multiple times Please help me check if this is an account issue, UEFN server/session issue, region issue, or a network/routing problem. I can provide the full log file if needed. Thank you. ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing? Matchmaking ### Steps to Reproduce 1. Open Unreal Editor for Fortnite. 2. Open my island/project. 3. Click Launch Session. 4. Fortnite opens and matchmaking/session setup starts. 5. After the session tries to connect to the Valkyrie Beacon, it times out and disconnects. ### Expected Result The UEFN session should launch successfully, Fortnite should connect to the playtest server, and I should be able to test my island normally. ### Observed Result The session fails after matchmaking completes. Fortnite shows “There was a problem” and “Network Connection Lost” with errors.com.epicgames.common.processing. In the UEFN log, I repeatedly get: ValkyrieBeaconClient ConnectionTimeout UNetConnection::Tick: Connection TIMED OUT Failed to connect to beacon Network error occurred when connecting to a server after matchmaking completed The timeout happens around 30 seconds after trying to connect to the beacon. ### Platform(s) windowsWindows PC ### Upload an image ![Screenshot_12.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/c/0/cc0609a294801b97829cc38119ef24ca039b344b.png) ![image(173).png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/0/4/50482d60acc8a0cc20df0475b3fd10eef5d97a94.png) ---

Hi @Flak , ist`s all the same problem and you see that many creators have this issue… I think you want to bundle all those issues in [Players can't join my map in public, Matchmaking error (errors.com.epicgames.common.processing)](https://forums.unrealengine.com/t/players-cant-join-my-map-in-public-matchmaking-error-errors-com-epicgames-common-processing/2725814) (but I think it`s not a suitable topic for that problem!) ---

Thanks, I was just looking for that link. Yes, we are aware and the team is checking into it. Going to close this one so it doesn’t create another ticket. @Abdulrehman-03 and @Lyraa - please post in that thread and vote on it. Thank you! ---
