Matchmaking Error #1

I am facing matchmaking errors on the island I am currently working on, which prevents me from accessing the private island. Unexpectedly, I find myself unable to access it, and I encounter the same issue during playtests. I believe that if I release this island, other players, aside from myself, will be faced with the same matchmaking error and won’t be able to play.
A month ago, I released another island and came across the exact same problem. I’ve filed bug reports, but the matchmaking error remains unresolved. On that island, both myself and other players rarely can match due to this error.
The islands I created and released more than two months ago don’t experience this issue. However, islands I’ve started creating since last month faces this problem, preventing me from functioning properly as a UEFN creator.
For some reason, there are times when matchmaking works, but when it doesn’t, even trying things like restarting Fortnite always results in an error.
I’ve put a lot of effort into the island I’m currently creating, so I earnestly request a resolution to this matchmaking error issue.

Is it possible that my settings or actions within UEFN are causing intermittent matchmaking errors?

The island currently experiencing this problem hasn’t been released yet.
