Hey y’all,

Had a quick question and wanted to see if anyone is seeing anything similar. After releasing our latest island version all users in both private and public lobbies are reporting receiving a Matchmaking Error #1.

After reverting the code and publishing again the error still persists on the most recent working version. The only time we can load into the island is to revert island versions to the last working build. This has made it so we can’t push any updates as we can’t deploy a working release.

Has anyone encountered anything similar? Is this something where specific Verse code could cause problems (we have a decent amount of custom code)?

Anything helps and thanks in advance!

Island code for reference (currently unlisted while we sort out what’s going on): 1875-2464-0254.

Hello. I’m experiencing the exact same issue; However, I haven’t been able to find a solution to it. Did you manage to solve this problem? I’d really appreciate an answer.

Hi Shadow, Welcome to the Forums.

I was able to load into the map mentioned above, so I wonder if @itsfield did anything specifically to resolve it…

Whenever I see someone mention Matchmaking Error #1 I like to check the map: 3815-8254-6961  
I currently still see the error on that map, and the only way I’ve ever been able to load into the map is with another person in my lobby.

So, I’m curious if you still see this issue with others in the lobby. Also I wonder if you changed any settings in IslandSettings Device → Matchmaking settings. (Changed settings will have an arrow next to them.)

Like Flak mentioned - You will want to add your info to + upvote [this thread](https://forums.unrealengine.com/t/urgent-island-passing-matchmaking-error-1-when-trying-to-queue/2684252).
