Help with my new game :(

I finished making my game yesterday and when i went to publish it it started lagging then it said this: POST "https://api.miniapps.ai/tools/b76fadd1- c925-4849-8c62- f5ecfb28a84b/publish": Load failed.

Idk what it means but its happen multiple times and i wanna fix it. my game its self is running perfectly but it just wont let me publish.
