Jumped onto UEFN today and tried launching a session. Was working earlier today but then it randomly decided to give me this issue within the last hour. Not sure how to fix. Tried restarting my launcher, signed in and out of my account. Restarted Fortnite. EDIT: This is using the LIVE version of Fortnite as requested earlier today ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/3/f/73fe90ede30650f9536bb64bc504bfe7ac35f11a.png) Here are my logs.

Hey @ImBlanky I notice the error message there shows you’re on 23.20… Live was updated to 23.30 last night so it’s possible you just caught the downtime while it was updating… Could you make sure Live is updated to 23.30 and give it another try? If you’re still seeing these issues we can troubleshoot further. Thanks! ---

Hey, I am still getting this error pretty much every time I launch for the first time. It usually goes away after 2-3 tries to launch session, but I’ve had a few times where it doesn’t and I have to restart. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/e/7/2e7ec874ef847226c432165829ae7107225e5462.png) ---

Yeah to follow up with BrendannnD, I’m still having this issue as well. Not sure what could be causing it. Started happening when we moved to LIVE build Have to press it about 2-5 times before it lets us through. ---

@BrendannnD @ImBlanky That’s interesting… I’ll have the team take a look asap for you! If you can could you post your UEFN/Client Logs after hitting this issue? Thanks! ---

I’m having the same problem in UEFN. [EDIT] All good, I didn’t update Fortnite, that’s why. ---

**Had the same problem a few times.** 1. Check if your Game has been Updated to the latest Version 2. If this is the case, restart the game and UEFN and that error will most likely disappear. Hope that helps 🙂 ---
