- Unreal Engine source build (4.25-plus branch)
- Plugin is installed from the Marketplace
When I tried using LoginWithCustomID last night and this morning, the return is all of a sudden giving me a 503 error saying that it "Could not contact server" and then the game crashes with a fatal error. It is not just my computer either, my testers have the same issue.
Nothing has changed except a title ID (now it's 3C019) but that has assuredly been changed everywhere it needs to be.
What causes this error and how do I fix it?
