Error 105

Since yesterday, I have been trying to upload my world, but I've been getting this same error message

"Upload

Sorry, an error occured!

ID: 105"

it will upload a bit and then it'll give an error message

I'm using version 1.15.2

I have tried this on both safari and chrome.

I even renamed it to " world "

But its still not working, please help

i cant find that, can you help

it worked when i changed my wifi, i used my hotspot and somehow it got uploaded. Maybe its my wifi problem
