I had this problem and it has nothing to do with Steam, or Valve servers. Read on and spread the word, 100% fix and proof.


I FINALLY after much searching and no results, figured out whu I was getting this.

The item publish tool doesn't connect to the internet itself. It makes a secure connection thanks to Steam.exe.

This can mean Web AV portion of some AV software will detect it as an injection or other unwanted connection unless allowed. Disabled for a moment and it uploaded first try.

I had tried 50 times for a couple of days on and off.. searched and found others with the problem and "it means time out just try later" and no better. Let anyone know who has this problem ! it is NOT STEAM SERVERS !
