I uploaded my first game to itch.io last month, and went to reinstall it just now. However, I'm getting this error: 

htfs.Open (inital request): in conn.Connect, non-retriable error: in conn.tryConnect, got HTTP non-2XX: api.itch.io: HTTP 400: {"errors":["missing token"]}

This is the game in question: https://stekken.itch.io/random-character-generator

It's free and published, and has installs from other users, so I'm not sure what could be wrong. 

Here's what I get when I click "view details", btw

I’m seeing it too with a different game.

I get the same issue regardless of what game I try to install, so it seems to be a fairly broad issue.

Looks like somebody’s opened a GitHub ticket for this: https://github.com/itchio/itch/issues/3327

I'm getting this with every game as of today in the Mac version of the app. Anyone had any luck yet?

any solution yet - I cant download any game anymore 

Exact same problem as you. Started since this morning (09/15/2025). Tried to download multiple games, hit with the same message.

this is also happening to me. I found another problem when trying to download the app itself. When you click start download it’s just brings you too a black screen and at the top right it says invalid file requested.

Same situation with me. App doesn't work. Web Browser does.

i have the same issue no matter what game i try to install. i have no idea what im supposed to do i tried looking for solutions but nothing helped

The same for me.  I can't download any of the games from the app

I can neither download Games from the Launcher on my Desktop PC, nor am i able to even download the Itch.IO Launcher to my Laptop. 
In the Itch Launcher i also receive the missing Token Error.
And when i try to download the Launcher App to my Laptop, it just shows me a blank Website with this sentence: "invalid File request".
