My map “Miner Tycoon 2” (2311-7649-8274) is also experiencing this issue, am getting many reports and I’ve experienced it myself for public lobbies. Switching to “Private” fixed it for me, but it doesn’t seem to be 100%

Can confirm I have the same issue, it’s either this or it gets stuck on preparing download for a really long time.

Hey folks, could we get some Fortnite logs here from people getting the error when trying to get in? Fortnite logs, not UEFN.

Same matchamaking error here! I haven’t had any players since the update, and I can’t access my map; it crashes after a while, saying “downloading”.

Same here, update has broken many things and I just published a map I had worked a long time on the day before :sob:

Hey Flak,

I have been experiencing this issue on my new map for a couple weeks now too. My map name is Midnight Massacre Halloween FFA (8942-1492-2947). It tries Finding Server for about 35 seconds and then throws a Matchmaking Error #1.

I have attached the logs you mentioned from trying to join a Public match on my map, of which was unsuccessful. Hope this helps and let me know if you need any additional information! Thanks.

upvote, stuck at 1% downloading for a 2 minutes or so and then error #2 we had trouble connecting to beacon device , uefn working fine.

11

My map 4194-5246-3286 has the same issue. Public matchmaking blocks sometimes at downloading updates and then at 1%.

12

can we get some progress already? it’s too risky to publish anything with this issue present

13

This thread might be related. This is a big issue we see across our maps as well.

14

In regards to that post I don’t use verse tags, material blocks or NPC definitions/NPCs. However I use complex scene graph and new UMG widget so maybe some of that is causing this issue, can’t tell

Hey @Flak We are also experiencing this issue on a brand collaboration we are working on with an upcoming deadline, we also still have this issue that was never solved on Kraken…

Cannot connect to any private versions on any device, launching a session works fine.

16

This line of code was causing it for us @Flak - Removing it fixes the issue

GetSession().Environment() <> session_environment.Live

17

GetSession() is the issue
