After uploading my project to a test code I am able to matchmake into the island for around 10-15 minutes, after roughly 10-15 minutes the project download size changes to “Unknown” in the creator dashboard. Matchmaking does not work from this point and will give an error stating “Network connection lost” or “Failed to build manifest for host”
I am also seeing a message regarding project size request in the message log which seems like it may be related to this separate issue. Failed to create project snapshot error
I tracked the issue down to one imported asset (A static Mesh) that was causing this error for me.
To do so I made a backup of my project, deleted every imported asset from the project folder on my pc and slowly re-added them while doing private code uploads between to see which assets would cause the version to corrupt.
You can keep track of which assets you re-added by making a note when uploading and then tracking which version the issue re-appears. Only assets loaded in the level and contributing to the download size will cause issues as far as I am aware.
It is a long process depending on how many imported assets you have but is sadly the only option we have right now it seems.
